NPM fails to install Socket.io does it need x-server?

Here is a quick how to for installing npm on Ubuntu, or any variant of UNIX for that matter

$ `curl http://npmjs.org/install.sh | sh` 

It is that simple!

So you want to check out the code from git and compile it yourself? Then follow these steps:

$ `git clone https://github.com/isaacs/npm` $ `cd npm` $ sudo make install 

Now you can install interesting stuff like socket.io

$ npm install socket.io 

X-server is not a dependency package of Socket.io...
