title: How can I reset my asset pipeline in Rails?
body: <p>Such a strange problem, but I deployed to production, and it won't update with my new CSS changes because of a caching issue.</p>
  
  <p>I tried this :</p>
  
  <pre><code>bundle exec rake assets:precompile
  </code></pre>
  
  <p>But that returns :</p>
  
  <pre><code>rake aborted!
  Don't know how to build task 'assets:precompile'
  </code></pre>
  
  <p>Ah, so I must be missing the sprockets in my application.rb perhaps. I tried everything on this link : <a href="https://stackoverflow.com/questions/7205964/dont-know-how-to-build-task-assetsprecompile">How to build task &#39;assets:precompile&#39;</a> . And every solution caused a load error for not finding the items that it pointed out.</p>
  
  <p>What should I do?</p>
  
  <p>Rails. 3.0.5</p>
