    I can confirm this running Ruby 1.8.7p249 and latest rubygems 1.8.7. #5499 claims you simply need latest rdoc but that doesn't work for me.

    jcm@jcm-desktop:~ > ruby -v && gem -v
    ruby 1.8.7 (2010-01-10 patchlevel 249) [x86_64-linux]
    jcm@jcm-desktop:~ > sudo gem update

    Confirming this for Ruby 1.8.7p302 with gem 1.3.7, except installing rdoc does fix it in my case:

    Vespasian:~$ sudo gem install rails
    File not found: lib
    Vespasian:~$ ruby -v
    ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin10]
    Vespasian:~$ sudo gem install rdoc rails
    Successfully installed rdoc-2.5.11
    Successfully installed rails-3.0.1
    2 gems installed
    Installing ri documentation for rdoc-2.5.11...
    Installing ri documentation for rails-3.0.1...
    Installing RDoc documentation for rdoc-2.5.11...
    Installing RDoc documentation for rails-3.0.1...

    Though the workaround is trivial, it's a pretty bad introduction to Rails. I saw the message "File not found: lib" followed by being returned to my shell and thought that the entire installation of Rails had failed. It wasn't until I did some searching and stumbled across this answer on Stack Overflow.

    This issue has been automatically marked as stale because it has not been commented on for at least three months.

    The resources of the Rails core team are limited, and so we are asking for your help. If you can still reproduce this error on the 3-0-stable branch or on master, please reply with all of the information you have about it and add "[state:open]" to your comment. This will reopen the ticket for review. Likewise, if you feel that this is a very important feature for Rails to include, please reply with your explanation so we can consider it.

    Thank you for all your contributions, and we hope you will understand this step to focus our efforts where they are most helpful.
