# 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 v0.4.1 release of node, do this:
nvm install v0.4.1
And then in any new shell just use the installed version:
nvm use v0.4.1
Or you can just run it:
nvm run v0.4.1
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 v0.4.1
## 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
