title: Cannot install Ruby Gems in Windows 7
body: <p>I have successfully installed Ruby Gems on my Mac many times.  I need to configure a Windows 7 Enterprise virtual machine with Compass, Sass and Suzy.</p>
  
  <p>I downloaded an installed Ruby on the Windows machine with the installer, 1.9.3.  I ran <code>gem update --system</code> which updated Rubygems to 1.8.4.</p>
  
  <p>I was able to install Sass 3.2 by running <code>gem install sass</code></p>
  
  <p>However, if I run <code>gem install compass</code> or <code>gem install susy</code> I get an error:</p>
  
  <pre><code>Error while excecuting gem .. (ArgumentError) marshall data too short
  </code></pre>
  
  <p>Any ideas?  At this point, I can't install those gems.</p>
