title: Python error while installing using homebrew
body: <p>Hi I installed python using "homebrew install python". 
  A script which was already running started throwing below error.</p>
  
  <pre><code>Traceback (most recent call last):
    File "TestConnection.py", line 1, in &lt;module&gt;
      from TextUpdater import TextUpdater
