title: Import Eve, but upon running run.py, says there is no module named eve
body: <p>I have recently begun looking at Eve. </p>
  
  <p>I have read the Eve <a href="http://python-eve.org/install.html" rel="nofollow">install guide</a> and imported it successfully. </p>
  
  <p>Then, I tried the <a href="http://python-eve.org/quickstart.html" rel="nofollow">quick start guide</a>, and made a few changes to the settings.py. When I try running run.py, it gives me this error:</p>
  
  <pre><code>Traceback (most recent call last):   File "run.py", line 1, in
  &lt;module&gt;     from eve import Eve ImportError: No module named eve
  </code></pre>
  
  <p>This is my code for run.py:</p>
  
  <pre><code>from eve import Eve
  app = Eve()
  
  if __name__ == '__main__':
      app.run()
  </code></pre>
  
  <p>And this is my code for settings.py</p>
  
  <pre><code>MONGO_HOST = 'localhost'
  MONGO_PORT = 27017
  
  MONGO_DBNAME = 'clownsighting'
  
  RESOURCE_METHODS = ['GET', 'POST', 'DELETE']

  schema = {

  <p>The two files are in the same directory, if that helps.</p>
