title: Get error when loading assets in Lotusrb
body: <p>I am trying out Lotusrb framework and I am having problems with assets. I followed the instructions for using in lotus from <a href="https://github.com/lotus/assets" rel="nofollow">lotus-assets in github</a> but I get the error <code>Errno::ENOENT: No such file or directory @ realpath_rec</code>.</p>
  
  <p>The error happens when I do:</p>
  
  <pre><code>Lotus::Assets.configure do
    compile true
  
    define :stylesheet do
      sources &lt;&lt; [
        'app/web/assets/stylesheets' # this is the path to my stylesheets
     ]
    end
  end
  </code></pre>
  
  <p>And then in my template:</p>
  
  <pre><code>&lt;%= stylesheet 'application' %&gt;
  </code></pre>
  
  <p>Don't know what I am doing wrong. Any help?</p>
