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

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!

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

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

Are you using the rinohtype extension too?

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

note: This error originates from a subprocess, and is likely not a problem with pip.

```

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~
