This is a fork
nvm using cnpm mirrors.
First you'll need to make sure your system has a c++ compiler. For OSX, XCode will work, for Ubuntu, the build-essential and libssl-dev packages work.
nvm does not support Windows (see #284). Two alternatives exist, which are neither supported nor developed by us:
- bass allows to use utilities written for Bash in fish shell
To install you could use the install script using cURL:
curl https://raw.githubusercontent.com/cnpm/nvm/master/install.sh | bash
wget -qO- https://raw.githubusercontent.com/cnpm/nvm/master/install.sh | bash
The script clones the nvm repository to
~/.nvm and adds the source line to your profile (
You can customize the install source, directory and profile using the
curl ... | NVM_DIR=/usr/local/nvm bash for a global install.
NB. The installer can use
wget to download
nvm, whatever is available.
For manual install create a folder somewhere in your filesystem with the
nvm.sh file inside it. I put mine in a folder called
Or if you have
git installed, then just clone it, and check out the latest version:
git clone https://github.com/cnpm/nvm.git ~/.nvm && cd ~/.nvm && git checkout `git describe --abbrev=0 --tags`
To activate nvm, you need to source it from your shell:
I always add this line to my
~/.zshrc file to have it automatically sourced upon login.
Often I also put in a line to use a specific version of node.
You can create an
.nvmrc file containing version number in the project root directory (or any parent directory).
nvm run, and
nvm which will all respect an
.nvmrc file when a version is not supplied.
To download, compile, and install the latest v0.10.x release of node, do this:
nvm install 0.10
And then in any new shell just use the installed version:
nvm use 0.10
Or you can just run it:
nvm run 0.10 --version
Or, you can run any arbitrary command in a subshell with the desired version of node:
nvm exec 0.10 node --version
You can also get the path to the executable to where it was installed:
nvm which 0.10
In place of a version pointer like "0.10", you can use the special default aliases "stable" and "unstable":
nvm install stable nvm install unstable nvm use stable nvm run unstable --version
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 v0.10.40 --reinstall-packages-from=0.10.39 nvm install v0.12.7 --reinstall-packages-from=0.12.6
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:
If you want to see what versions are available to install:
To restore your PATH, you can deactivate it.
To set a default Node version to be used in any new shell, use the alias 'default':
nvm alias default stable
To use a mirror of the node binaries, set
export NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 0.10 NVM_NODEJS_ORG_MIRROR=https://nodejs.org/dist nvm install 0.10
To use a mirror of the iojs binaries, set
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.

Tests are written in Urchin. Install Urchin (and other dependencies) like so:
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
Nota bene: Avoid running nvm while the tests are running.
To activate, you need to source
[[ -r $NVM_DIR/bash_completion ]] && . $NVM_DIR/bash_completion
Put the above sourcing line just below the sourcing line for NVM in your profile (
$ 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 [tab][tab] default $ nvm alias my_alias [tab][tab] v0.6.21 v0.8.26 v0.10.28
$ nvm use [tab][tab] my_alias default v0.6.21 v0.8.26 v0.10.28
$ 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:
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
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
