title: Installing Rails engine gem - path not found
body: <p>I've been following the guide around rails engines here: <a href="http://guides.rubyonrails.org/engines.html" rel="nofollow noreferrer">http://guides.rubyonrails.org/engines.html</a> and have created the example engine <code>blorgh</code> and also have a barebones rails app.</p>
  
  <p>I generated my engine following this command: </p>
  
  <p><code>rails plugin new blorgh --mountable</code></p>
  
  <p>And I can confirm that I have: <code>/lib/blorgh.rb</code> in my engine. Now going by the guides it states you simply need to add the following to your main app: </p>
  
  <p><code>gem 'blorgh', path: 'engines/blorgh'</code>. Now in my main rails app when I try to do <code>bundle install</code> I get: </p>
  
  <blockquote>
    <p>The path <code>/Users/home/projects/unicorn/engines/blorgh</code> does not exist.</p>
  </blockquote>
  
  <p>I'm pretty sure I'm missing something basic here.</p>
