Cannot import Munch if the wheel doesn't come from a regular source

[sebastienwood]

Hi !
Munch is a dependancy in a project of mine. When loaded in an env. where the wheels are locally provided, it cannot be imported properly as we see in the following traceback:

Traceback (most recent call last):
File "/home/script.py", line 7, in
import munch
File "/localscratch/temp_instance/env/lib/python3.8/site-packages/munch/init.py", line 29, in
VERSION = tuple(map(int, version.split('.')[:3]))
ValueError: invalid literal for int() with base 10: '0+computecanada'

I observe similar issues in an pipenv: ValueError: invalid literal for int() with base 10: 'unknown'
