title: Change in python script not reflected when I execute module "behave"
body: <p>I am trying to use Behave from terminal.
  Typing <code>behave</code> in terminal, I received an error,</p>
  <blockquote>
  <p>Exception ImportError: No module named worker</p>
  <p>File &quot;features/environment.py&quot;, line 11, in &lt;module&gt;</p>
  <p>from worker import glob, json</p>
  <p>ImportError: No module named worker</p>
  </blockquote>
  <p>I have made the change in my environment.py document and removed the <code>from worker import glob, json</code>.</p>
  <p>However when I execute behave, I receive the same error.
  I closed terminal, reopened it. I closed the text editor (Atom) and reopened it. The error persists. When I restarted the computer, it finally reflected the changes. I do not want to restart the computer every time to get behave to show the document changes.</p>
  <p>Why is this happening and what can be done?</p>
