NodeJS installation for Ubuntu 14.04

Some packages needed for binary builds:

sudo apt-get update
sudo apt-get install build-essential libssl-dev

First install NVM (Node Version Manager) for your OS. Mine is Ubuntu so:

curl https://raw.githubusercontent.com/creationix/nvm/v0.16.1/install.sh | sh

Now install node last version (today is v0.12.0):

nvm install -s v0.12.0
nvm alias default v0.12.0

This will take a while because you are compiling sources (-s option)

Installing Bower

Bower allows you to install and manage the dependencies of a lot of JS libraries found in its marketplace:

npm install -g bower
