It's a conflict with flake8 for Python 3.7

mvaled commented 6 months ago

@arcivanov I'm seeing this error on Python 3.12 without flake8 installed.

Here is myrequirements file:

requirements-dev.txt

From what I see in the docs of importlib.metadata there's no method .get for this collection. Instead there's a select method to get the entry points.

Calling it returns this:

>>> metadata.entry_points().select(group="markdown.extensions")
