  <p>This is my application.html.erb</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;

  <p>The error message says that the error occurs at line 6:</p>
  
  <pre><code>&lt;%= javascript_include_tag 'application', 'data-turbolinks-track' =&gt; true %&gt;
  </code></pre>
  
  <p>So this leads me to believe my javascript is not loading properly...</p>
  
  <p>I am using Minitest, here is my controller test:</p>
  
  <pre><code>require "test_helper"
  
  class CategoriesControllerTest &lt; ActionController::TestCase
  
      def test_new
          get :new
          assert_response :success
      end
  
  end
  </code></pre>
  
  <p>I have also created a new.html.erb view that is mostly blank except for some dummy text:</p>
  
  <pre><code>This is my new file! #This is inside my views/categories/new.html.erb
  </code></pre>
  
  <p>Here is my controller:</p>
  
  <pre><code>class CategoriesController &lt; ApplicationController
  
      def new
      end
  
  end
  </code></pre>
  
  <p>When I turn on rails server and I navigate to my root/categories/new route I get the following error message:</p>
  
  <pre><code>Errno::ENOENT in Categories#new
  Showing c:/Users/Javi/desktop/rails_projects/testing_basics/app/views/layouts/application.html.erb where line #6 raised:
  
  No such file or directory @ unlink_internal - C:/Users/Javi/AppData/Local/Temp/execjs20150429-4112-xc20tpjson

  </code></pre>
  
  <p>Can someone please help me figure this out? I have been stuck on this for 2 full days. I have tried downgrading execjs gem version but still get the error. I have also restarted from scratch and get the same error at the same place. Not sure what else to do now... </p>
