title: Sprockets not found 'Jquery-ujs'
body: <p>My rails local server is struggling to find the jquery-ujs files. How do I fix this?</p>
  
  <p>application.js</p>
  
  <pre><code>//= require jquery
  //= require jquery-ujs
  //= require jquery-ui
  //= require bootstrap
  </code></pre>
  
  <p>and finally my gemfile currently:</p>
  
  <pre><code>gem 'jquery-rails', '2.3.0'
  gem 'jquery-ui-rails'
  </code></pre>
  
  <p>When I run the local server I get the error:</p>
  
  <pre><code>Sprockets::FileNotFound: couldn't find file 'jquery-ujs'
  </code></pre>
