title: Could not find rake-10.0.4 in any of the sources (Bundler::GemNotFound)
body: <p>I have been trying to run my ruby application on the server recently and I keep coming across this error:</p>
  
  <pre><code>Could not find rake-10.0.4 in any of the sources (Bundler::GemNotFound)
  </code></pre>
  
  <p>I am running Rails 3.2.12 and Ruby 1.9.3p392. Until now I have not had any problems when accessing the server, and this is the first time I have come across this error.</p>
  
  <p>I have tried looking around for answers, but as I am relatively new to ruby and rails I couldn't find an answer that was simple to understand.</p>
