title: Sprockets::FileNotFound: couldn't find file 'jquery-ui'?
body: <p>I'm writing a Rails project, and using <code>rvm ruby-1.9.3-p362</code>. </p>
  
  <p>In my gemfile I have:</p>
  
  <pre><code>ruby 1.9.3
  gem 'rails', '3.1.0' 
  gem 'jquery-rails'
  gem 'jquery-ui-rails'
  </code></pre>
  
  <p>I also do <code>bundle install</code> and restart the Rails server, but when I'm running it in the browser it gets a console error.</p>
  
  <pre><code>Sprockets::FileNotFound: couldn't find file 'jquery-ui'
  </code></pre>
  
  <p>How can I make it work?</p>
