- Installing nvm on Alpine Linux
- Problems
First you'll need to make sure your system has a c++ compiler. For OS X, Xcode will work, for Ubuntu, the build-essential
and libssl-dev
packages work.
Note: nvm
does not support Windows (see #284). Two 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
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:
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 withnpm -g
, so instead of doingsudo npm install -g grunt
, do insteadnpm install -g grunt
- If you have an
~/.npmrc
file, make sure it does not contain anyprefix
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, so the minimum required git version is v1.7.0 and we recommend v1.7.9.5 as it's the default version of the wildly used Ubuntu 12.04 LTS. If you are interested in the problem we mentioned here, please refer to GitHub's HTTPS cloning errors article.
To install or update nvm, you can use the install script using cURL:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash
or Wget:
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | bash
The script clones the nvm repository to ~/.nvm
and adds the source line to your profile (~/.bash_profile
, ~/.zshrc
, ~/.profile
, or ~/.bashrc
).
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
You can customize the install source, directory, profile, and version using the NVM_SOURCE
, NVM_DIR
, PROFILE
, and NODE_VERSION
variables.
Eg: curl ... | NVM_DIR=/usr/local/nvm bash
for a global install.
NB. The installer can use git
, curl
, or wget
to download nvm
, whatever is available.
Note: On OS X, if you get nvm: command not found
after running the install script, your system may not have a [.bash_profile file] where the command is set up. Simply create one with touch ~/.bash_profile
and run the install script again.
If the above doesn't fix the problem, open your .bash_profile
and add the following line of code:
source ~/.bashrc
- For more information about this issue and possible workarounds, please refer here
To verify that nvm has been installed, do:
command -v nvm
which should output 'nvm' if the installation was successful. Please note that which nvm
will not work, since nvm
is a sourced shell function, not an executable binary.
For manual install create a folder somewhere in your filesystem with the nvm.sh
file inside it. I put mine in ~/.nvm
.
Or if you have git
installed (requires git v1.7+):
- clone this repo
- check out the latest version
- activate nvm by sourcing it from your shell
export NVM_DIR="$HOME/.nvm" && (
git clone https://github.com/creationix/nvm.git "$NVM_DIR"
cd "$NVM_DIR"
git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" origin`
) && . "$NVM_DIR/nvm.sh"
Add these lines to your ~/.bashrc
, ~/.profile
, or ~/.zshrc
file to have it automatically sourced upon login:
(you may have to add to more than one of the above files)
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
For manual upgrade with git
(requires git v1.7+):
- change to the
$NVM_DIR
- pull down the latest changes
- check out the latest version
- activate the new version
(
cd "$NVM_DIR"
git fetch origin
git checkout `git describe --abbrev=0 --tags --match "v[0-9]*" origin`
) && . "$NVM_DIR/nvm.sh"
To download, compile, and install the latest release of node, do this:
nvm install node
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 5.0
In place of a version pointer like "0.10" or "5.0" or "4.2.1", 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 ofnode
iojs
: this installs the latest version ofio.js
stable
: this alias is deprecated, and only truly applies tonode
v0.12
and earlier. Currently, this is an alias fornode
.unstable
: this alias points tonode
v0.11
- the last "unstable" node release, since post-1.0, all node versions are stable. (in semver, versions communicate breakage, not stability).
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.
If you want to install a new version of Node.js and migrate npm packages from a previous version:
nvm install node --reinstall-packages-from=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 6 --reinstall-packages-from=5
nvm install v4.2 --reinstall-packages-from=iojs
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 iojs --reinstall-packages-from=iojs
The same guidelines mentioned for migrating npm packages in Node.js are applicable to io.js.
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
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
To restore your PATH, you can deactivate it:
nvm deactivate
To set a default Node version to be used in any new shell, use the alias 'default':
nvm alias default node
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.
You can create a .nvmrc
file containing version number in the project root directory (or any parent directory).
nvm use
, nvm install
, nvm exec
, nvm run
, and nvm which
will all respect an .nvmrc
file when a version is not supplied.
For example, to make nvm default to the latest 5.9 release for the current directory:
$ echo "5.9" > .nvmrc
$ echo "lts/*" > .nvmrc # to default to the latest LTS version
Then when you run nvm:
$ nvm use
Found '/path/to/project/.nvmrc' with version <5.9>
Now using node v5.9.1 (npm v3.7.3)
You can use avn
to deeply integrate into your shell and automatically invoke nvm
when changing directories. avn
is not supported by the nvm
development team. Please report issues to the avn
team.
If you prefer a lighter-weight solution, the recipes below have been contributed by nvm
users. They are not supported by the nvm
development team. We are, however, accepting pull requests for more examples.
Put this into your $HOME/.zshrc
to call nvm use
automatically whenever you enter a directory that contains an
.nvmrc
file with a string telling nvm which node to use
:
# place this after nvm initialization!
autoload -U add-zsh-hook
load-nvmrc() {
local node_version="$(nvm version)"
local nvmrc_path="$(nvm_find_nvmrc)"
if [ -n "$nvmrc_path" ]; then
local nvmrc_node_version=$(nvm version "$(cat "${nvmrc_path}")")
if [ "$nvmrc_node_version" != "N/A" ] && [ "$nvmrc_node_version" != "$node_version" ]; then
nvm install
fi
elif [ "$node_version" != "$(nvm version default)" ]; then
echo "Reverting to nvm default version"
nvm use default
fi
}
add-zsh-hook chpwd load-nvmrc
load-nvmrc

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.
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
).
nvm:
$ nvm [tab][tab]
alias deactivate install ls run unload
clear-cache exec list ls-remote unalias use
current help list-remote reinstall-packages uninstall version
nvm alias:
$ nvm alias [tab][tab]
default
$ nvm alias my_alias [tab][tab]
v0.6.21 v0.8.26 v0.10.28
nvm use:
$ nvm use [tab][tab]
my_alias default v0.6.21 v0.8.26 v0.10.28
nvm uninstall:
$ nvm uninstall [tab][tab]
my_alias default v0.6.21 v0.8.26 v0.10.28
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
In order to provide the best performance (and other optimisations), 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 pre-these 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 but currently (May 2016), this is not available for Node versions newer than v0.10 so unless you need an older Node version, this won't help you. Work is in progress on source-builds for newer Node versions but is not yet complete.
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:
apk add bash
wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.32.1/install.sh | /bin/bash
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.
If you try to install a node version and the installation fails, be sure to delete the node downloads from src (~/.nvm/src/) or you might get an error when trying to reinstall them again 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 this link:
On Arch Linux and other systems using python3 by default, before running install you need to:
export PYTHON=python2
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)
