hi,
(maybe this is off topic on this list)
When I want to run sphinx cmd on my pc, I got the error:
```

TypeError: expected string or bytes-like object
```
The problem may be in importlib_metadata here, but I am not sure how to fix it.
I remembered I do `python setup.py build/install` something ago.
Any help is welcome!

BR,
Bo

Looks like this: https://github.com/sphinx-doc/sphinx/issues/10339

Are you using the rinohtype extension too?

I noticed it also but I did not remember use sphinx with rinohtype
extension.

The fact is that I am packaging the sphinxcontrib-ditaa[0] and I want to
test it via pip3:

```
vimer@dev:~/build/rfs/packages/test_dir$ sudo pip3 install  sphinxcontrib-ditaa
Collecting sphinxcontrib-ditaa

```

So I think the issue maybe not raised from sphinx extension, but it could be worse than that.

Thanks for help:)

You are right. The traceback is indeed different but more similar to 
this one, probably: https://github.com/pypa/setuptools/issues/3273

I have tried to make an empty .dist-info dir and got the very similar 
result to yours.

The following command may help to locate the actual offending package:

strace -eopenat python -c "from importlib.metadata import entry_points; 
print(entry_points(group='sphinx.builders'))"

Great! It works.

I deleted the package that was installed by setup.py with above command
hint. Everythng is well now.

Many thanks~
