title: Vanishing Ruby Gems
body: <p>I'm using Ubuntu 8.10 and I installed Ruby and Ruby on Rails following the directions on <a href="http://wiki.rubyonrails.org/getting-started/installation/linux" rel="nofollow noreferrer">this</a> site. The exact directions I followed are no longer there as it appears the rubyonrails.org wiki has changed recently. But I installed it the long way. Installed Ruby, then Gems, then installed Rails using "gem install rails".
  I haven't really messed with Rails for a while, and I tried to use the Gem command today and...</p>
  
  <pre><code>   The program 'gem' can be found in the following packages:
      * rubygems1.8
      * rubygems1.9
     Try: sudo apt-get install &lt;selected package&gt;
     bash: gem: command not found
  </code></pre>
  
  <p>That's just weird to me because I installed rails using the gem command. I have been seaching my computer for the gems binary so I could create a link to it in the bin directory but I can't find it. I know it's installed becaues when I run 'script/server' and go to localhost:3000 in a browser I get the following version information:</p>
  
  <pre><code>Ruby version    1.8.7 (i486-linux)
  RubyGems version    1.3.1
  Rails version   2.2.2
  Active Record version   2.2.2
  Action Pack version 2.2.2
  Active Resource version 2.2.2
  Action Mailer version   2.2.2
  Active Support version  2.2.2
  </code></pre>
  
  <p>Anyone know how I can get my gem command working again? Thanks for any help.</p>
  
  <p>Note: I am new to Rails and fairly new to Ubuntu and Linux in general.</p>
