title: Using rubyzip error - no such file to load -- zip/zip
body: <p>I know there is another thread on this subject but I still face this problem even after using all solutions. Is there any other way to generate zip files? Can i use Ubuntu system commands? </p>
  
  <p>I did</p>
  
  <pre><code> gem install rubyzip
  </code></pre>
  
  <p>I have</p>
  
  <pre><code>require 'rubygems'
  require 'zip/zip'
  </code></pre>
  
  <p>in my controller</p>
  
  <p>But i still get the same error - no such file to load -- zip/zip
  I tried with both ruby 1.8.7 and ruby 1.9.2 with rails 3.0.5 on Ubuntu</p>
  
  <p>Could you please help me? Thanks.</p>
