Initial install on Ubuntu 13 and CentOS 6.4

[Viktor Godard]

What are the pre-requisites for the Ruby environment before I can work with ec2launcher? It doesn't seem to work with the default install environments on Ubuntu 13 or Centos 6.4...

Good question.

Ruby 1.9.3 is definitely supported. I have not yet tested Ruby 2.0 and I haven't tried 1.9.2. I definitely know that 1.8.7 does not work.

CentOS only ships with Ruby 1.8.7 (gah!) and I believe Ubuntu 13 ships with Ruby 2.0. I use RVM with Ruby 1.9.3-p194, although I believe I have also used Ruby 1.9.3-p392 successfully as well.

Try installing RVM and then install Ruby 1.9.3:

rvm install ruby-1.9.3

Source the appropriate RVM script based on your installation and then install ec2launcher:

gem install ec2launcher
