python2 python3 messed up : How to fix ?

[Gribouillis]

The strange thing in your error message is this

Error:
File "/usr/lib/python3.8/collections/init.py", line 27, in
from reprlib import recursive_repr as _recursive_repr
File "/home/harold/.local/lib/python2.7/site-packages/reprlib/init.py", line 7, in

When the standard module 'collections' from python 3.8 library tries to import the stardard module 'reprlib', it imports it from /home/harold/.local/lib/python2.7/site-packages, that is to say from the python 2.7 library insteado of importing it from python 3.8's library. For me it means that at this moment, the directory /home/harold/.local/lib/python2.7/site-packages is mistakenly in the sys.path list.

I suggest that at the very top of genVersion.py, you add temporarily this line to see what sys.path contains when this line is executed. Then see if it contains a python 2.7 directory

import sys
raise RuntimeError(sys.path)
