What RubyGems version, and what OS? If you could give us the output of
gem envthat would be awesome.3 Posted by rwallace_88 on 14 Jun, 2011 01:12 PM

Hello,
Sorry for the delay on the answer. Seems to me that you're having issues retrieving the list of gems from rubygems.org
Can you please perform:
gem sources -cgem list railsand see it is not installed.Now, please execute the following command:
gem install rails --debug -V, please create a pastie or gist with the complete output and update this ticket with the link for us to look at.Thank you.
