title: Install a specific Ruby on Rails version on Windows
body: <p>Normally I use:</p>
  
  <pre><code>gem install rails
  </code></pre>
  
  <p>I can install Rails on Windows, but by default, I guess the latest version, version 3.0.3 is installed.</p>
  
  <p>So if I want to install some other version of Rails, let's say 3.0.1, how can I do it?</p>
