title: Why is Ninja-ide unable to see the installed version of sip?
body: <p>am trying to install and run Ninja-ide.  I have followed the instructions in the documentation <a href="http://ninja-ide.readthedocs.org/en/latest/installing.html" rel="nofollow">here</a></p>
  
  <p>I move to the Ninja-ide folder and run the suggested command:</p>
  
  <pre><code>$ python ninja-ide.py
  </code></pre>
  
  <p>and get the following:</p>
  
  <pre><code>XXXX-XXXX-MacBook-Pro:ninja-ide twmeggs$ python ninja-ide.py
  Traceback (most recent call last):
    File "ninja-ide.py", line 26, in &lt;module&gt;
      import ninja_ide
    File "/Users/XXXX/ninja-ide/ninja_ide/__init__.py", line 48, in &lt;module&gt;
  import sip
  ImportError: No module named sip
  </code></pre>
  
  <p>so I try to re-install sip with:</p>
  
  <pre><code>XXXX-XXXX-MacBook-Pro:ninja-ide $ brew install sip
  </code></pre>
  
  <p>only to be told that it's already installed:</p>
  
  <pre><code>Error: sip-4.13.3 already installed
  </code></pre>
  
  <p>Now, I will hold my hands up here and say that I'm only just getting used to using a shell to execute commands and only just getting used to the files/directory/folder layouts within a Mac, so it's completely possible that I've messed up something simple here.</p>
  
  <p>If someone could offer some help, or even a nudge in the right direction it would be much appreciated.</p>
  
  <p>Thanks </p>
