title: No module named '_tkinter' on Mac using Python 3
body: <p>I'm trying to bundle my script into a .app using Tkinter as the GUI and the wrapper that does the bundling is Platypus. </p>
  
  <p>I'm getting this error when I go to run the app.</p>
  
  <pre><code>Traceback (most recent call last):
  File "/Users/samb/Desktop/Beta1.app/Contents/Resources/script", line 4, in &lt;module&gt;
    import tkinter
  File "/Applications/Xcode.app/Contents/Developer/Library/Frameworks/P...ework/Versions/3.7/lib/python3.7/tkinter/__init__.py", line 36, in &lt;module&gt;
    import _tkinter # If this fails your Python may not be configured for Tk
  ModuleNotFoundError: No module named '_tkinter'
  </code></pre>
  
  <p>I'm running Python 3.7.4 on this machine, and my script uses:</p>
  
  <pre><code>import tkinter
  from tkinter import filedialog
  </code></pre>
  
  <p>which should make it compatible. The script works when I run it using terminal, just not when I run the app. </p>

  <p>I've specified in the bundling app that it should use python3 as well...</p>
  
  <p>Not sure what I'm doing wrong here?</p>
