When installing Rails 3.0.1 i always get following error message, although i can use the installation.
I'm not sure if there's something wrong, I'm irritated by the error message.

As in the answer by balupton:
Ruby on Rails Beta 3 Install Problem on Snow Leopard
gem install rdoc
Follow instructions and then rerun
gem install rails
No errors occur to me now.

Still the same problem and solution even with latest Ubuntu and Rails 4.0.0, I guess fixing it wouldn't be a bad idea for next rails versions, the error message should be made informative. – matanster Jul 11 '13 at 06:40

I had a similar problem today. Serpenstage's answer helped and lead me to find this guide here. http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac
It installs RVM too, which is useful for running multiple versions of ruby.

Did you install Ruby before installing rails? I ran into the same problem until I went to https://help.ubuntu.com/community/RubyOnRails#Get%20Ruby. There are a number of steps you have to take before you install rails and I think this will help, if you are running it on the Ubuntu OS. Hope it works for you!
