`run` command runs given node version without modyfing global state:
[maciej@PC07 nvm (run)]$ node --version
v0.4.12
[maciej@PC07 nvm (run)]$ nvm run 0.4.12
Running node v0.4.12
> process.version
'v0.4.12'
> [maciej@PC07 nvm (run)]$ nvm run 0.5.9
Running node v0.5.9
> process.version

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
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
