title: Keep error message of exe file which is created by Pyinstaller
body: <p>I am using Pyinstaller to create exe file from Python source code, and I keep the cmd window when the exe is running</p>
  
  <pre><code>python pyinstaller.py --onefile script.py
  </code></pre>
  
  <p>Whenever there is an error, the error shows on the cmd window but disappears very quickly, is there any way to keep the error message on the cmd window?</p>
