sudo apt-get install python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs

You must install a server site js compiler like node.js or an other solution is adding ‘therubyracer’, ‘>= 0.8.2’ at gemfile.

gem 'therubyracer', '>= 0.8.2'
