I’m trying to use the Mongoid / Devise Rails 3.1 template (Mongoid and Devise), and I keep getting an error stating ExecJS cannot find a JavaScript runtime. Fair enough when I didn’t have any installed, but I’ve tried installing Node.js, Mustang and the Ruby Racer, but nothing is working.
I could not find a JavaScript runtime. See sstephenson/ExecJS (GitHub) for a list of available runtimes (ExecJS::RuntimeUnavailable).
What do I need to do to get this working?

As of Ubuntu 13.04 x64 you only need to run:
This will solve the problem.
