AttributeError: 'zipimporter' object has no attribute 'exec_module'

in certain python environments (foundry nuke python 3.9.10) markdown fails to import with:

File "site-packages\shiboken2\files.dir\shibokensupport_feature_.py", line 142, in import
return original_import(name, *args, **kwargs)
File "site-packages\markdown_init.py", line 22, in
from .core import Markdown, markdown, markdownFromFile
File "site-packages\shiboken2\files.dir\shibokensupport_feature_.py", line 142, in import
return original_import(name, *args, **kwargs)
File "site-packages\markdown\core.py", line 27, in
from .preprocessors import build_preprocessors
File "site-packages\shiboken2\files.dir\shibokensupport_feature.py", line 142, in import
return original_import(name, *args, **kwargs)
File "site-packages\markdown\preprocessors.py", line 29, in
from .htmlparser import HTMLExtractor
File "site-packages\shiboken2\files.dir\shibokensupport_feature.py", line 142, in _import
return original_import(name, *args, **kwargs)
File "site-packages\markdown\htmlparser.py", line 31, in
spec.loader.exec_module(htmlparser)
AttributeError: 'zipimporter' object has no attribute 'exec_module'

we have downgraded markdown to 3.1.1 and this fixed the issue.
we actually don't know if the problem is on the foundry side or markdown package. reporting here in case other ppl have similar issues.

I think it's a bug in pyside2/shiboken, not in Python-Markdown.

I have seen something similar when packaging pyside2 for Debian. I ended up using this patch from ArchLinux which solved all import problems. Maybe it will help for you too: https://github.com/archlinux/svntogit-packages/blob/packages/pyside2/trunk/fix-build.patch
