Installing NodeJS and NPM

I will be installing NodeJS 4.1.0 on ubuntu 11.04.

Requirements

• sudo apt-get install open-ssl libssl-dev

Get the archive
wget http://nodejs.org/dist/node-v0.4.10.tar.gz

Unpack the archive
tar zxvf node-v0.4.10.tar.gz ; cd node-v0.4.10/


Configure the compiler and install
sudo ./configure && sudo make && sudo make install


Finally, install NPM.  This you must do as root, otherwise it gets messy
sudo su -
curl http://npmjs.org/install.sh | sh
