This weekend, I decided to give Ruby on Rails a go, considering I just finished school and I’ll have plenty of free time to explore.
Hello, I just thought I’d post something as I had the same problem on Windows.
I tried running the command “gem install rails –source http://gem.rubyonrails.org” but I received the error: “actionpack requires rack (>= 0.9.0, runtime)”
So I ran “gem install rack” which installed something
And then “gem install rails –source http://gem.rubyonrails.org” and it installed 2.3.0 just fine.
Based on this post: http://railsforum.com/viewtopic.php?pid=89050
I also changed my rails version in environment.rb to “2.3.0” and renamed “application.rb” to “application_controller.rb” and everything is working. Thanks a bunch for the info!
