title: Trying to create symlink - keep getting error: "File exists"
body: <p>I am trying to use <a href="http://pow.cx/" rel="nofollow">Pow</a> and create a symlink so that I can ultimately run my rails application locally at the following URL:</p>
  
  <p><a href="http://market_place_api.dev/" rel="nofollow">http://market_place_api.dev/</a></p>
  
  <p>I am going through the <a href="http://apionrails.icalialabs.com/book" rel="nofollow">API's on Rails tutorial</a>, and when I follow the <a href="http://apionrails.icalialabs.com/book/chapter_one#sec-pow_prax" rel="nofollow">author's instructions</a> on setting up Pow and a symlink, here is what is happening:</p>
  
  <ol>
  <li>cd into a folder called "code", and created a new rails app: <code>$ rails new market_place_api -T</code></li>
  <li>Installed Pow: <code>$ curl get.pow.cx | sh</code></li>
  <li>Gone to the Pow directory: <code>$ cd ~/.pow</code></li>
  <li><strong>And here is where the problem occurs.</strong>  The instructions say to symlink: <code>$ ln -s /path/to/myapp</code></li>
  <li>In my case, the app is located at this URL:  <code>/Users/harrylevine/Dropbox/Coding/BLOC/code/market_place_api</code></li>
  <li>So I enter into the command line: <code>$ ln -s /Users/harrylevine/Dropbox/Coding/BLOC/code/market_place_api</code> and I keep getting <strong>this error:</strong> <code>ln: ./market_place_api: File exists</code></li>
  </ol>
  
  <p>I have tried many variations of this, including:</p>
  
  <ul>
  <li>applying this format:  <code>ln -s target_path link_path</code></li>
  </ul>
  
  <p>All to no avail.</p>
  
  <p>How can I properly create this symlink so that I can ultimately run my rails application locally at the following URL:</p>
