Working with Ruby on the MC 10 systems

While it is possible to install Ruby on a system-wide basis, it is much more common amongst the Ruby community to use a tool called rvm (Ruby Version Manager) to build and install Ruby and to manage the installation of Ruby gems (libraries). This tutorial will get you started with RVM on the MC 10 systems.

Prerequisites

This tutorial assumes:

• You are working on one of the Linux systems in MC 10. Do not attempt this on obelix.
• You have at least 100 - 200 MB of free space in your GAUL account, depending on the Ruby gems that you install. You have at least 1 GB of quota, so this shouldn't be much of a hardship for you. If you need more quota to make this work, contact Jeff at [x@y, where x = jeff, y = csd.uwo.ca].
