Node Version Manager

Intro

nvm allows you to quickly install and use different versions of node via the command line.

Example:

$ nvm use 16
Now using node v16.9.1 (npm v7.21.1)
$ node -v
v16.9.1
$ nvm use 14
Now using node v14.18.0 (npm v6.14.15)
$ node -v
v14.18.0
$ nvm install 12
Now using node v12.22.6 (npm v6.14.5)
$ node -v
v12.22.6

Simple as that!

About

nvm is a version manager for node.js, designed to be installed per-user, and invoked per-shell. nvm works on any POSIX-compliant shell (sh, dash, ksh, zsh, bash), in particular on these platforms: unix, macOS, and windows WSL.

Installing and Updating

Install & Update Script

To install or update nvm, you should run the install script. To do that, you may either download and run the script manually, or use the following cURL or Wget command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Running either of the above commands downloads a script and runs it. The script clones the nvm repository to ~/.nvm, and attempts to add the source lines from the snippet below to the correct profile file (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

Additional Notes

If the environment variable $XDG_CONFIG_HOME is present, it will place the nvm files there.
You can add --no-use to the end of the above script (...nvm.sh --no-use) to postpone using nvm until you manually use it.
You can customize the install source, directory, profile, and version using the NVM_SOURCE, NVM_DIR, PROFILE, and NODE_VERSION variables. Eg: curl ... | NVM_DIR="path/to/nvm". Ensure that the NVM_DIR does not contain a trailing slash.
The installer can use git, curl, or wget to download nvm, whichever is available.
You can instruct the installer to not edit your shell config (for example if you already get completions via a zsh nvm plugin) by setting PROFILE=/dev/null before running the install.sh script. Here's an example one-line command to do that: PROFILE=/dev/null bash -c 'curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash'

Troubleshooting on Linux

On Linux, after running the install script, if you get nvm: command not found or see no feedback from your terminal after you type command -v nvm, simply close your current terminal, open a new terminal, and try verifying again. Alternatively, you can run the following commands for the different shells on the command line:

bash: source ~/.bashrc

zsh: source ~/.zshrc

ksh: . ~/.profile

These should pick up the nvm command.

Troubleshooting on macOS

Since OS X 10.9, /usr/bin/git has been preset by Xcode command line tools, which means we can't properly detect if Git is installed or not. You need to manually install the Xcode command line tools before running the install script, otherwise, it'll fail. (see #1782)

If you get nvm: command not found after running the install script, one of the following might be the reason:

Since macOS 10.15, the default shell is zsh and nvm will look for .zshrc to update, none is installed by default. Create one with touch ~/.zshrc and run the install script again.
If you use bash, the previous default shell, your system may not have .bash_profile or .bashrc files where the command is set up. Create one of them with touch ~/.bash_profile or touch ~/.bashrc and run the install script again. Then, run . ~/.bash_profile or . ~/.bashrc to pick up the nvm command.
You have previously used bash, but you have zsh installed. You need to manually add these lines to ~/.zshrc and run . ~/.zshrc.
You might need to restart your terminal instance or run . ~/.nvm/nvm.sh. Restarting your terminal/opening a new tab/window, or running the source command will load the command and the new configuration.
If the above didn't help, you might need to restart your terminal instance. Try opening a new tab/window in your terminal and retry.

If the above doesn't fix the problem, you may try the following:

If you use bash, it may be that your .bash_profile (or ~/.profile) does not source your ~/.bashrc properly. You could fix this by adding source ~/<your_profile_file> to it or following the next step below.
Try adding the snippet from the install section, that finds the correct nvm directory and loads nvm, to your usual profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc).
For more information about this issue and possible workarounds, please refer here

Note For Macs with the Apple Silicon chip, node started offering arm64 arch Darwin packages since v16.0.0 and experimental arm64 support when compiling from source since v14.17.0. If you are facing issues installing node using nvm, you may want to update to one of those versions or later.

Ansible

You can use a task:

- name: Install nvm
  ansible.builtin.shell: >
    curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
  args:
    creates: "{{ ansible_env.HOME }}/.nvm/nvm.sh"

Verify Installation

To verify that nvm has been installed, do:

command -v nvm

which should output nvm if the installation was successful. Please note that which nvm will not work, since nvm is a sourced shell function, not an executable binary.

Note: On Linux, after running the install script, if you get nvm: command not found or see no feedback from your terminal after you type command -v nvm, simply close your current terminal, open a new terminal, and try verifying again.

Important Notes

If you're running a system without prepackaged binary available, which means you're going to install node or io.js from its source code, you need to make sure your system has a C++ compiler. For OS X, Xcode will work, for Debian/Ubuntu based GNU/Linux, the build-essential and libssl-dev packages work.

Note: nvm also supports Windows in some cases. It should work through WSL (Windows Subsystem for Linux) depending on the version of WSL. It should also work with GitBash (MSYS) or Cygwin. Otherwise, for Windows, a few alternatives exist, which are neither supported nor developed by us:

Note: nvm does not support Fish either (see #303). Alternatives exist, which are neither supported nor developed by us:

bass allows you to use utilities written for Bash in fish shell
fast-nvm-fish only works with version numbers (not aliases) but doesn't significantly slow your shell startup
plugin-nvm plugin for Oh My Fish, which makes nvm and its completions available in fish shell
fnm - fisherman-based version manager for fish
fish-nvm - Wrapper around nvm for fish, delays sourcing nvm until it's actually used.

Note: We still have some problems with FreeBSD, because there is no official pre-built binary for FreeBSD, and building from source may need patches; see the issue ticket:

Note: On OS X, if you do not have Xcode installed and you do not wish to download the ~4.3GB file, you can install the Command Line Tools. You can check out this blog post on how to just that:

How to Install Command Line Tools in OS X Mavericks & Yosemite (Without Xcode)

Note: On OS X, if you have/had a "system" node installed and want to install modules globally, keep in mind that:

When using nvm you do not need sudo to globally install a module with npm -g, so instead of doing sudo npm install -g grunt, do instead npm install -g grunt
If you have an ~/.npmrc file, make sure it does not contain any prefix settings (which is not compatible with nvm)
You can (but should not?) keep your previous "system" node install, but nvm will only be available to your user account (the one used to install nvm). This might cause version mismatches, as other users will be using /usr/local/lib/node_modules/* VS your user account using ~/.nvm/versions/node/vX.X.X/lib/node_modules/*

Homebrew installation is not supported. If you have issues with homebrew-installed nvm, please brew uninstall it, and install it using the instructions below, before filing an issue.

Note: If you're using zsh you can easily install nvm as a zsh plugin. Install zsh-nvm and run nvm upgrade to upgrade.

Note: Git versions before v1.7 may face a problem of cloning nvm source from GitHub via https protocol, and there is also different behavior of git before v1.6, and git prior to v1.17.10 can not clone tags, so the minimum required git version is v1.7.10. If you are interested in the problem we mentioned here, please refer to GitHub's HTTPS cloning errors article.

Git Install

If you have git installed (requires git v1.7.10+):

clone this repo in the root of your user profile
- cd ~/ from anywhere then git clone https://github.com/nvm-sh/nvm.git .nvm
cd ~/.nvm and check out the latest version with git checkout v0.40.1
activate nvm by sourcing it from your shell: . ./nvm.sh

Now add these lines to your ~/.bashrc, ~/.profile, or ~/.zshrc file to have it automatically sourced upon login: (you may have to add to more than one of the above files)

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Manual Install

For a fully manual install, execute the following lines to first clone the nvm repository into $HOME/.nvm, and then load nvm:

export NVM_DIR="$HOME/.nvm" && (
  git clone https://github.com/nvm-sh/nvm.git "$NVM_DIR"
  cd "$NVM_DIR"
  git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)`
) && \. "$NVM_DIR/nvm.sh"

Now add these lines to your ~/.bashrc, ~/.profile, or ~/.zshrc file to have it automatically sourced upon login: (you may have to add to more than one of the above files)

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

Manual Upgrade

For manual upgrade with git (requires git v1.7.10+):

change to the $NVM_DIR
pull down the latest changes
check out the latest version
activate the new version

(
  cd "$NVM_DIR"
  git fetch --tags origin
  git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" $(git rev-list --tags --max-count=1)`
) && \. "$NVM_DIR/nvm.sh"

Usage

To download, compile, and install the latest release of node, do this:

nvm install node # "node" is an alias for the latest version

To install a specific version of node:

nvm install 14.7.0 # or 16.3.0, 12.22.1, etc

To set an alias:

nvm alias my_alias v14.4.0

Make sure that your alias does not contain any spaces or slashes.

The first version installed becomes the default. New shells will start with the default version of node (e.g., nvm alias default).

You can list available versions using ls-remote:

nvm ls-remote

And then in any new shell just use the installed version:

nvm use node

Or you can just run it:

nvm run node --version

Or, you can run any arbitrary command in a subshell with the desired version of node:

nvm exec 4.2 node --version

You can also get the path to the executable to where it was installed:

nvm which 12.22

In place of a version pointer like "14.7" or "16.3" or "12.22.1", you can use the following special default aliases with nvm install, nvm use, nvm run, nvm exec, nvm which, etc:

node: this installs the latest version of node
iojs: this installs the latest version of io.js
stable: this alias is deprecated, and only truly applies to node v0.12 and earlier. Currently, this is an alias for node.
unstable: this alias points to node v0.11 - the last "unstable" node release, since post-1.0, all node versions are stable. (in SemVer, versions communicate breakage, not stability).

Long-term Support

Node has a schedule for long-term support (LTS) You can reference LTS versions in aliases and .nvmrc files with the notation lts/* for the latest LTS, and lts/argon for LTS releases from the "argon" line, for example. In addition, the following commands support LTS arguments:

nvm install --lts / nvm install --lts=argon / nvm install 'lts/*' / nvm install lts/argon
nvm uninstall --lts / nvm uninstall --lts=argon / nvm uninstall 'lts/*' / nvm uninstall lts/argon
nvm use --lts / nvm use --lts=argon / nvm use 'lts/*' / nvm use lts/argon
nvm exec --lts / nvm exec --lts=argon / nvm exec 'lts/*' / nvm exec lts/argon
nvm run --lts / nvm run --lts=argon / nvm run 'lts/*' / nvm run lts/argon
nvm ls-remote --lts / nvm ls-remote --lts=argon nvm ls-remote 'lts/*' / nvm ls-remote lts/argon
nvm version-remote --lts / nvm version-remote --lts=argon / nvm version-remote 'lts/*' / nvm version-remote lts/argon

Any time your local copy of nvm connects to https://nodejs.org, it will re-create the appropriate local aliases for all available LTS lines. These aliases (stored under $NVM_DIR/alias/lts), are managed by nvm, and you should not modify, remove, or create these files - expect your changes to be undone, and expect meddling with these files to cause bugs that will likely not be supported.

To get the latest LTS version of node and migrate your existing installed packages, use

nvm install --reinstall-packages-from=current 'lts/*'

Migrating Global Packages While Installing

If you want to install a new version of Node.js and migrate npm packages from a previous version:

nvm install --reinstall-packages-from=node node

This will first use "nvm version node" to identify the current version you're migrating packages from. Then it resolves the new version to install from the remote server and installs it. Lastly, it runs "nvm reinstall-packages" to reinstall the npm packages from your prior version of Node to the new one.

You can also install and migrate npm packages from specific versions of Node like this:

nvm install --reinstall-packages-from=5 6
nvm install --reinstall-packages-from=iojs v4.2

Note that reinstalling packages explicitly does not update the npm version — this is to ensure that npm isn't accidentally upgraded to a broken version for the new node version.

To update npm at the same time add the --latest-npm flag, like this:

nvm install --reinstall-packages-from=default --latest-npm 'lts/*'

or, you can at any time run the following command to get the latest supported npm version on the current node version:

nvm install-latest-npm

If you've already gotten an error to the effect of "npm does not support Node.js", you'll need to (1) revert to a previous node version (nvm ls & nvm use <your latest _working_ version from the ls>), (2) delete the newly created node version (nvm uninstall <your _broken_ version of node from the ls>), then (3) rerun your nvm install with the --latest-npm flag.

Default Global Packages From File While Installing

If you have a list of default packages you want installed every time you install a new version, we support that too -- just add the package names, one per line, to the file $NVM_DIR/default-packages. You can add anything npm would accept as a package argument on the command line.

# $NVM_DIR/default-packages

rimraf
object-inspect@1.0.2

io.js

If you want to install io.js:

nvm install iojs

If you want to install a new version of io.js and migrate npm packages from a previous version:

nvm install --reinstall-packages-from=iojs iojs

The same guidelines mentioned for migrating npm packages in node are applicable to io.js.

System Version of Node

If you want to use the system-installed version of node, you can use the special default alias "system":

nvm use system
nvm run system --version

Listing Versions

If you want to see what versions are installed:

nvm ls

If you want to see what versions are available to install:

nvm ls-remote

Setting Custom Colors

You can set five colors that will be used to display version and alias information. These colors replace the default colors. Initial colors are: g b y r e

Color codes:

r/R = red / bold red

g/G = green / bold green

b/B = blue / bold blue

c/C = cyan / bold cyan

m/M = magenta / bold magenta

y/Y = yellow / bold yellow

k/K = black / bold black

e/W = light grey / white

nvm set-colors rgBcm

Persisting custom colors

If you want the custom colors to persist after terminating the shell, export the NVM_COLORS variable in your shell profile. For example, if you want to use cyan, magenta, green, bold red and bold yellow, add the following line:

export NVM_COLORS='cmgRY'

Suppressing colorized output

nvm help (or -h or --help), nvm ls, nvm ls-remote and nvm alias usually produce colorized output. You can disable colors with the --no-colors option (or by setting the environment variable TERM=dumb):

nvm ls --no-colors
nvm help --no-colors
TERM=dumb nvm ls

Restoring PATH

To restore your PATH, you can deactivate it:

nvm deactivate

Set default node version

To set a default Node version to be used in any new shell, use the alias 'default':

nvm alias default node # this refers to the latest installed version of node
nvm alias default 18 # this refers to the latest installed v18.x version of node
nvm alias default 18.12  # this refers to the latest installed v18.12.x version of node

Use a mirror of node binaries

To use a mirror of the node binaries, set $NVM_NODEJS_ORG_MIRROR:

export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist
nvm install node

NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 4.2

To use a mirror of the io.js binaries, set $NVM_IOJS_ORG_MIRROR:

export NVM_IOJS_ORG_MIRROR=https://iojs.org/dist
nvm install iojs-v1.0.3

NVM_IOJS_ORG_MIRROR=https://iojs.org/dist nvm install iojs-v1.0.3

nvm use will not, by default, create a "current" symlink. Set $NVM_SYMLINK_CURRENT to "true" to enable this behavior, which is sometimes useful for IDEs. Note that using nvm in multiple shell tabs with this environment variable enabled can cause race conditions.

Pass Authorization header to mirror

To pass an Authorization header through to the mirror url, set $NVM_AUTH_HEADER

NVM_AUTH_HEADER="Bearer secret-token" nvm install node

.nvmrc

You can create a .nvmrc file containing a node version number (or any other string that nvm understands; see nvm --help for details) in the project root directory (or any parent directory). Afterwards, nvm use, nvm install, nvm exec, nvm run, and nvm which will use the version specified in the .nvmrc file if no version is supplied on the command line.

For example, to make nvm default to the latest 5.9 release, the latest LTS version, or the latest node version for the current directory:

$ echo "5.9" > .nvmrc

$ echo "lts/*" > .nvmrc # to default to the latest LTS version

$ echo "node" > .nvmrc # to default to the latest version

[NB these examples assume a POSIX-compliant shell version of echo. If you use a Windows cmd development environment, eg the .nvmrc file is used to configure a remote Linux deployment, then keep in mind the "s will be copied leading to an invalid file. Remove them.]

Then when you run nvm use:

$ nvm use
Found '/path/to/project/.nvmrc' with version <5.9>
Now using node v5.9.1 (npm v3.7.3)

Running nvm install will also switch over to the correct version, but if the correct node version isn't already installed, it will install it for you.

$ nvm install
Found '/path/to/project/.nvmrc' with version <5.9>
Downloading and installing node v5.9.1...
Downloading https://nodejs.org/dist/v5.9.1/node-v5.9.1-linux-x64.tar.xz...
#################################################################################### 100.0%
Computing checksum with sha256sum
Checksums matched!
Now using node v5.9.1 (npm v3.7.3)

nvm use et. al. will traverse directory structure upwards from the current directory looking for the .nvmrc file. In other words, running nvm use et. al. in any subdirectory of a directory with an .nvmrc will result in that .nvmrc being utilized.

The contents of a .nvmrc file must contain precisely one <version> (as described by nvm --help) followed by a newline. .nvmrc files may also have comments. The comment delimiter is #, and it and any text after it, as well as blank lines, and leading and trailing white space, will be ignored when parsing.

Key/value pairs using = are also allowed and ignored, but are reserved for future use, and may cause validation errors in the future.

Run npx nvmrc to validate an .nvmrc file. If that tool’s results do not agree with nvm, one or the other has a bug - please file an issue.

Deeper Shell Integration

You can use avn to deeply integrate into your shell and automatically invoke nvm when changing directories. avn is not supported by the nvm maintainers. Please report issues to the avn team.

You can also use nvshim to shim the node, npm, and npx bins to automatically use the nvm config in the current directory. nvshim is not supported by the nvm maintainers. Please report issues to the nvshim team.

If you prefer a lighter-weight solution, the recipes below have been contributed by nvm users. They are not supported by the nvm maintainers. We are, however, accepting pull requests for more examples.

Calling `nvm use` automatically in a directory with a `.nvmrc` file

In your profile (~/.bash_profile, ~/.zshrc, ~/.profile, or ~/.bashrc), add the following to nvm use whenever you enter a new directory:

bash

Put the following at the end of your $HOME/.bashrc:

cdnvm() {
    command cd "$@" || return $?
    nvm_path="$(nvm_find_up .nvmrc | command tr -d '\n')"

    # If there are no .nvmrc file, use the default nvm version
    if [[ ! $nvm_path = *[^[:space:]]* ]]; then

        declare default_version
        default_version="$(nvm version default)"

        # If there is no default version, set it to `node`
        # This will use the latest version on your machine
        if [ $default_version = 'N/A' ]; then
            nvm alias default node
            default_version=$(nvm version default)
        fi

        # If the current version is not the default version, set it to use the default version
        if [ "$(nvm current)" != "${default_version}" ]; then
            nvm use default
        fi
    elif [[ -s "${nvm_path}/.nvmrc" && -r "${nvm_path}/.nvmrc" ]]; then
        declare nvm_version
        nvm_version=$(<"${nvm_path}"/.nvmrc)

        declare locally_resolved_nvm_version
        # `nvm ls` will check all locally-available versions
        # If there are multiple matching versions, take the latest one
        # Remove the `->` and `*` characters and spaces
        # `locally_resolved_nvm_version` will be `N/A` if no local versions are found
        locally_resolved_nvm_version=$(nvm ls --no-colors "${nvm_version}" | command tail -1 | command tr -d '\->*' | command tr -d '[:space:]')

        # If it is not already installed, install it
        # `nvm install` will implicitly use the newly-installed version
        if [ "${locally_resolved_nvm_version}" = 'N/A' ]; then
            nvm install "${nvm_version}";
        elif [ "$(nvm current)" != "${locally_resolved_nvm_version}" ]; then
            nvm use "${nvm_version}";
        fi
    fi
}

alias cd='cdnvm'
cdnvm "$PWD" || exit

This alias would search 'up' from your current directory in order to detect a .nvmrc file. If it finds it, it will switch to that version; if not, it will use the default version.

zsh

This shell function will install (if needed) and nvm use the specified Node version when an .nvmrc is found, and nvm use default otherwise.

Put this into your $HOME/.zshrc to call nvm use automatically whenever you enter a directory that contains an .nvmrc file with a string telling nvm which node to use:

# place this after nvm initialization!
autoload -U add-zsh-hook

load-nvmrc() {
  local nvmrc_path
  nvmrc_path="$(nvm_find_nvmrc)"

  if [ -n "$nvmrc_path" ]; then
    local nvmrc_node_version
    nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")")

    if [ "$nvmrc_node_version" = "N/A" ]; then
      nvm install
    elif [ "$nvmrc_node_version" != "$(nvm version)" ]; then
      nvm use
    fi
  elif [ -n "$(PWD=$OLDPWD nvm_find_nvmrc)" ] && [ "$(nvm version)" != "$(nvm version default)" ]; then
    echo "Reverting to nvm default version"
    nvm use default
  fi
}

add-zsh-hook chpwd load-nvmrc
load-nvmrc

fish

This requires that you have bass installed.

# ~/.config/fish/functions/nvm.fish
function nvm
  bass source ~/.nvm/nvm.sh --no-use ';' nvm $argv
end

# ~/.config/fish/functions/nvm_find_nvmrc.fish
function nvm_find_nvmrc
  bass source ~/.nvm/nvm.sh --no-use ';' nvm_find_nvmrc
end

# ~/.config/fish/functions/load_nvm.fish
function load_nvm --on-variable="PWD"
  set -l default_node_version (nvm version default)
  set -l node_version (nvm version)
  set -l nvmrc_path (nvm_find_nvmrc)
  if test -n "$nvmrc_path"
    set -l nvmrc_node_version (nvm version (cat $nvmrc_path))
    if test "$nvmrc_node_version" = "N/A"
      nvm install (cat $nvmrc_path)
    else if test "$nvmrc_node_version" != "$node_version"
      nvm use $nvmrc_node_version
    end
  else if test "$node_version" != "$default_node_version"
    echo "Reverting to default Node version"
    nvm use default
  end
end

# ~/.config/fish/config.fish
# You must call it on initialization or listening to directory switching won't work
load_nvm > /dev/stderr

Running Tests

Tests are written in Urchin. Install Urchin (and other dependencies) like so:

npm install

There are slow tests and fast tests. The slow tests do things like install node and check that the right versions are used. The fast tests fake this to test things like aliases and uninstalling. From the root of the nvm git repository, run the fast tests like this:

npm run test/fast

Run the slow tests like this:

npm run test/slow

Run all of the tests like this:

npm test

Nota bene: Avoid running nvm while the tests are running.

Environment variables

nvm exposes the following environment variables:

NVM_DIR - nvm's installation directory.
NVM_BIN - where node, npm, and global packages for the active version of node are installed.
NVM_INC - node's include file directory (useful for building C/C++ addons for node).
NVM_CD_FLAGS - used to maintain compatibility with zsh.
NVM_RC_VERSION - version from .nvmrc file if being used.

Additionally, nvm modifies PATH, and, if present, MANPATH and NODE_PATH when changing versions.

Bash Completion

To activate, you need to source bash_completion:

[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion

Put the above sourcing line just below the sourcing line for nvm in your profile (.bashrc, .bash_profile).

Usage

nvm:

$ nvm Tab

alias               deactivate          install             list-remote         reinstall-packages  uninstall           version
cache               exec                install-latest-npm  ls                  run                 unload              version-remote
current             help                list                ls-remote           unalias             use                 which

Compatibility Issues

nvm will encounter some issues if you have some non-default settings set. (see #606) The following are known to cause issues:

Inside ~/.npmrc:

prefix='some/path'

Environment Variables:

$NPM_CONFIG_PREFIX
$PREFIX

Shell settings:

set -e

Installing nvm on Alpine Linux

In order to provide the best performance (and other optimizations), nvm will download and install pre-compiled binaries for Node (and npm) when you run nvm install X. The Node project compiles, tests and hosts/provides these pre-compiled binaries which are built for mainstream/traditional Linux distributions (such as Debian, Ubuntu, CentOS, RedHat et al).

Alpine Linux, unlike mainstream/traditional Linux distributions, is based on BusyBox, a very compact (~5MB) Linux distribution. BusyBox (and thus Alpine Linux) uses a different C/C++ stack to most mainstream/traditional Linux distributions - musl. This makes binary programs built for such mainstream/traditional incompatible with Alpine Linux, thus we cannot simply nvm install X on Alpine Linux and expect the downloaded binary to run correctly - you'll likely see "...does not exist" errors if you try that.

There is a -s flag for nvm install which requests nvm download Node source and compile it locally.

If installing nvm on Alpine Linux is still what you want or need to do, you should be able to achieve this by running the following from you Alpine Linux shell, depending on which version you are using:

Alpine Linux 3.13+

apk add -U curl bash ca-certificates openssl ncurses coreutils python3 make gcc g++ libgcc linux-headers grep util-linux binutils findutils
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Alpine Linux 3.5 - 3.12

apk add -U curl bash ca-certificates openssl ncurses coreutils python2 make gcc g++ libgcc linux-headers grep util-linux binutils findutils
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash

Note: Alpine 3.5 can only install NodeJS versions up to v6.9.5, Alpine 3.6 can only install versions up to v6.10.3, Alpine 3.7 installs versions up to v8.9.3, Alpine 3.8 installs versions up to v8.14.0, Alpine 3.9 installs versions up to v10.19.0, Alpine 3.10 installs versions up to v10.24.1, Alpine 3.11 installs versions up to v12.22.6, Alpine 3.12 installs versions up to v12.22.12, Alpine 3.13 & 3.14 install versions up to v14.20.0, Alpine 3.15 & 3.16 install versions up to v16.16.0 (These are all versions on the main branch). Alpine 3.5 - 3.12 required the package python2 to build NodeJS, as they are older versions to build. Alpine 3.13+ requires python3 to successfully build newer NodeJS versions, but you can use python2 with Alpine 3.13+ if you need to build versions of node supported in Alpine 3.5 - 3.15, you just need to specify what version of NodeJS you need to install in the package install script.

The Node project has some desire but no concrete plans (due to the overheads of building, testing and support) to offer Alpine-compatible binaries.

As a potential alternative, @mhart (a Node contributor) has some Docker images for Alpine Linux with Node and optionally, npm, pre-installed.

Uninstalling / Removal

Manual Uninstall

To remove nvm manually, execute the following:

First, use nvm unload to remove the nvm command from your terminal session and delete the installation directory:

$ nvm_dir="${NVM_DIR:-~/.nvm}"
$ nvm unload
$ rm -rf "$nvm_dir"

Edit ~/.bashrc (or other shell resource config) and remove the lines below:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion

Docker For Development Environment

To make the development and testing work easier, we have a Dockerfile for development usage, which is based on Ubuntu 18.04 base image, prepared with essential and useful tools for nvm development, to build the docker image of the environment, run the docker command at the root of nvm repository:

$ docker build -t nvm-dev .

This will package your current nvm repository with our pre-defined development environment into a docker image named nvm-dev, once it's built with success, validate your image via docker images:

$ docker images

REPOSITORY         TAG                 IMAGE ID            CREATED             SIZE
nvm-dev            latest              9ca4c57a97d8        7 days ago          650 MB

If you got no error message, now you can easily involve in:

$ docker run -h nvm-dev -it nvm-dev

nvm@nvm-dev:~/.nvm$

Please note that it'll take about 8 minutes to build the image and the image size would be about 650MB, so it's not suitable for production usage.

For more information and documentation about docker, please refer to its official website:

Problems

If you try to install a node version and the installation fails, be sure to run nvm cache clear to delete cached node downloads, or you might get an error like the following:

curl: (33) HTTP server doesn't seem to support byte ranges. Cannot resume.
Where's my sudo node? Check out #43
After the v0.8.6 release of node, nvm tries to install from binary packages. But in some systems, the official binary packages don't work due to incompatibility of shared libs. In such cases, use -s option to force install from source:

nvm install -s 0.8.6

If setting the default alias does not establish the node version in new shells (i.e. nvm current yields system), ensure that the system's node PATH is set before the nvm.sh source line in your shell profile (see #658)

macOS Troubleshooting

nvm node version not found in vim shell

If you set node version to a version other than your system node version nvm use 6.2.1 and open vim and run :!node -v you should see v6.2.1 if you see your system version v0.12.7. You need to run:

sudo chmod ugo-x /usr/libexec/path_helper

WSL Troubleshooting

If you've encountered this error on WSL-2:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.1/install.sh | bash
% Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                Dload  Upload  Total   Spent    Left  Speed
0     0    0     0    0     0      0      0 --:--:--  0:00:09 --:--:--     0curl: (6) Could not resolve host: raw.githubusercontent.com

It may be due to your antivirus, VPN, or other reasons.

Where you can ping 8.8.8.8 while you can't ping google.com

This could simply be solved by running this in your root directory:

sudo rm /etc/resolv.conf
sudo bash -c 'echo "nameserver 8.8.8.8" > /etc/resolv.conf'
sudo bash -c 'echo "[network]" > /etc/wsl.conf'
sudo bash -c 'echo "generateResolvConf = false" >> /etc/wsl.conf'
sudo chattr +i /etc/resolv.conf

This deletes your resolv.conf file that is automatically generated when you run WSL, creates a new file and puts nameserver 8.8.8.8, then creates a wsl.conf file and adds [network] and generateResolveConf = false to prevent auto-generation of that file.

You can check the contents of the file by running:

cat /etc/resolv.conf
