title: Trouble getting Jekyll Themes served on local machine (could not find addressable...)
body: <p>Been playing around with Jekyll for a few days now, but haven't been having any lucky trying to get themes working on my local machine.</p>
  
  <p>I've tried several different themes and am getting errors that seem to be pointing towards missing files??? I'm not entirely sure as I'm completely new to Ruby.</p>
  
  <h2>What I've got installed</h2>
  
  <ul>
  <li>ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]</li>
  <li>jekyll 3.4.3</li>
  </ul>
  
  <h2>What commands I'm running</h2>
  
  <pre><code>~ $ cd ~/jekyll-theme/
  ~ $ jekyll serve
  </code></pre>
  
  <h2>Error and Trace</h2>

  <h2>Attemps</h2>
  
  <p>I've tried issuing the following command:<br>
  <code>~ $ bundle exec jekyll serve</code>
  resulting in the same error and trace<br></p>
  
  <p>Any insight is greatly appreciated.</p>
