Node Version Manager

Installation

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.

To install create a folder somewhere in your filesystem with the "nvm.sh" file inside it. I put mine in a folder called "nvm".

Or if you have git installed, then just clone it:

git clone git://github.com/creationix/nvm.git ~/nvm

To activate nvm, you need to source it from your bash shell

. ~/nvm/nvm.sh

I always add this line to my ~/.bashrc or ~/.profile file to have it automatically sources upon login.
Often I also put in a line to use a specific version of node.

Usage

To download, compile, and install the v0.6.14 release of node, do this:

nvm install v0.6.14

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

nvm use v0.6.14

Or you can just run it:

nvm run v0.6.14

If you want to see what versions are available:

nvm ls

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 0.6

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][tab]
alias          copy-packages  help           list           run            uninstall      version        
clear-cache    deactivate     install        ls             unalias        use

nvm alias

$ nvm alias [tab][tab]
default

$ nvm alias my_alias [tab][tab]
v0.4.11        v0.4.12       v0.6.14

nvm use

$ nvm use [tab][tab]
my_alias        default        v0.4.11        v0.4.12       v0.6.14

nvm uninstall

$ nvm uninstall [tab][tab]
my_alias        default        v0.4.11        v0.4.12       v0.6.14

Problems

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'? Checkout this link:

on Arch Linux and other systems using python3 by default, before running install you need to

  export PYTHON=python2
