As you are using Rails 3, you have a good option after installing rails is to run "bundle install" command from your application, this will install all required gems for you.
Another note, I faced many cases in Rails 3 that installation of gems fail, and after some researching, the solutions was to add --no-ri --no-rdoc to the installation command. For example, if you want to install rails gem install rails --no-ri --no-rdoc Regards, Ahmed -----Original Message----- From: rubyonrails-talk@googlegroups.com [mailto:rubyonrails-t...@googlegroups.com] On Behalf Of Peter Vandenabeele Sent: Wednesday, December 29, 2010 12:19 AM To: rubyonrails-talk@googlegroups.com Subject: [Rails] gem install of rails-3.0.3 on ruby-1.8.7-p330 gives rdoc error On Ubuntu 10.04 with rvm 1.1.7 and the "Christmas" rubies: * I get the ERROR messages below for a "fresh" 'gem install rails' on ruby-1.8.7-p330 * I get a clean install of rails 3.0.3 on ruby-1.9.2-p136 (see below) pet...@asus:~$ rvm --version rvm 1.1.7 by Wayne E.
