Updated Ruby Switcher: Working With Multiple Ruby Versions Has Never Been This Easy

Posted by jasonrudolph on July 29, 2009 — 4 comments
The Ruby Switcher is a super-lightweight tool for quickly switching between Ruby versions. You can easily experiment with Ruby 1.9 to try out a gem or two, and if you run into issues, you can safely retreat back to 1.8.x (after you report the Ruby 1.9 problems to the gem's maintainers, of course). The latest version includes single-line commands that install the various Ruby versions for you. Wanna try out Ruby 1.9.1? Just type install_ruby_191, and the Ruby Switcher handles the rest. The Ruby Switcher gives you shell-specific Ruby versions: while one terminal window is testing out a gem or app in Ruby 1.9, you can have another terminal performing the same tests with Ruby 1.8.7 (or JRuby, or Ruby 1.8.6, or REE, or Leopard Ruby, etc.). When switching between Ruby versions is this seamless, there’s no reason not to experiment.

“” This is terrific (Although I did have a problem installing REE, and sent you the 'relevance' user on GitHub an email about that, a pointer to a bug tracker and casino en ligne would be nice).And you'll be happy to note that I tested a gem project I manage and discovered a couple of tiny incompatibilities with 1.9.1 which are now fixed and the gem is tested in 1.8.6, 1.8.7, 1.9.1 and Leopard Ruby. I feel much better now. Thanks.piplu - October 11, 2010 13:00
