What's the bad magic number error?

Question

What\'s the \"Bad magic number\" ImportError in python, and how do I fix it?

The only thing I can find online suggests this is caused by compiling a .py -> .pyc file

Answer 1

In my case, I've git clone a lib which had an interpreter of

#!/usr/bin/env python

While python was leading to Python2.7 even though my main code was running with python3.6 ... it still created a *.pyc file for 2.7 version ...

I can say that this error probably is a result of a mix between 2.7 & 3+ versions, this is why cleanup ( in any way you can think of that you're using ) - will help here ...

• don't forget to adjust those Python2x code -> python 3...
