    copied!<p>I followed <a href="http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/" rel="nofollow">this instruction</a> to install Ruby on Rails on my ubuntu 11.04, but always got this error message:</p> <pre><code>feicun@feicun-ubuntu:~$ gem install rails Successfully installed rails-3.0.9 1 gem installed Installing ri documentation for rails-3.0.9... file 'lib' not found Installing RDoc documentation for rails-3.0.9... file 'lib' not found </code></pre> <p>I googled this problem, which means the documentations could not be build, but rails 3.0.9 is installed.
