I've also reported the problem here: psf/requests#6331
But I think it's more appropriate to get it fixed in PyInstaller.

Also hit by this, will likely work around it for now by pinning older version of charset_normalizer.

Moving the issue to contrib hooks repository, where we will add a hook (and a test) for the charset_normalizer.

Until then, use --hiddenimport charset_normalizer.md__mypyc with your PyInstaller command.

I've gone ahead and hit the release button in the hopes that I won't be receiving a new duplicate of this bug report each day for the next two weeks.

pip install "pyinstaller-hooks-contrib>=2022.15"

i'm running PyInstaller==5.10.1, and I still have to use this work around --hiddenimport charset_normalizer.md__mypyc

mentioned here.
#534 (comment)

If this was reported against 5.7 and was "merged" how is this not currently fixed?

I can only show this at runtime after the .exe is built.
File "PyInstaller\loader\pyimod02_importers.py", line 352, in exec_module File "charset_normalizer\cd.py", line 9, in <module> ModuleNotFoundError: No module named 'charset_normalizer.md__mypyc' [12748] Failed to execute script 'main' due to unhandled exception!

and the above errors go away when i compile with --hiddenimports

The fix is in the hooks repo so it's pyinstaller-hooks-contrib you need to upgrade.

I guess I did not properly upgrade. I modified my spec file to set hidden imports back to an empty list, hiddenimports=[],

the new generated EXE worked.

Now I understand what you meant by pip install "pyinstaller-hooks-contrib>=2022.15"

current working versions for me.

pyinstaller==5.10.1
pyinstaller-hooks-contrib==2023.2

Thanks!
