To update ruby version used by a ruby on rails app we need to start with installing the ruby version we want.

This can be accomplished very easy with Ruby Version Manager (RVM).

Likewise, if you frequently work on more than one computer, a hosted environment eliminates the difficulty of maintaining duplicate development environments.

For these reasons some developers prefer to “work in the cloud” using Cloud9.

You’ll need superuser (root) access to update the system software.

Update your package manager first: on freenode requires registration (see how to register).

I recommend to manage Ruby versions and gems because it is popular, well-supported, and full-featured.Since Rails 3.1, a Java Script runtime has been needed for development on Ubuntu Linux.The Java Script runtime is required to compile code for the Rails asset pipeline.Any computer can access the hosted development environment, though you’ll need a broadband connection. Using a hosted environment means you are no longer dependent on the physical presence of a computer that stores all your files.If your computer crashes or is stolen, you can continue to use your hosted environment from any other computer.
