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
