# 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
