KeyError: 'pop from an empty set'

Not sure how this happened, but here's the stack trace in pybind11-stubgen 2.4.1:

pybind11_stubgen - [WARNING] Enum-like str representations were found with no matching mapping to the enum class location.
Use `--enum-class-locations` to specify full path to the following enum(s):

Thanks for the report!

Now I'm looking closer to #196, there are a few problems there. I'll not be able to quickly address it. I'm thinking of reverting #196, unfortunately.

Should be solved by #203

@virtuald for my understanding of the origin of this bug... were you using --enum-class-locations when this error occurred? Does it still occur even when you don't use it? (using v2.4.1)

[virtuald]

@ringohoffman I did not specify --enum-class-locations. I have an automated binding tool called robotpy-build which calls stubgen to generate pyi files (see https://github.com/robotpy/robotpy-build/blob/main/robotpy_build/command/build_pyi.py#L152).

I was likely building https://github.com/robotpy/mostrobotpy/ ... but I'm not 100% sure which one of the subprojects I was building. You can do RPYBUILD_PARALLEL=1 ./rdev.sh ci run to build all of the projects, it takes awhile.
