Other Additional Information:

A solution would be to replace enum_tools/custom_enums.py#L50 with the Python main branch implementation

Hi @zevaryx, sorry about that. The CPython developers decided postpone the changes to the enum module until 3.11 which is what broke the import.

It should be sorted in version 0.6.5. Can you try that version, and if it works for you I'll close the issue.

I'm having the same issue with Python 3.12.4 and enum_tools@0.9.0-post1

Traceback (most recent call last):

~How can I fix this?~ 0.9.0-post1 has the import, 0.9.0 doesn't have it. Needs a bump of enum-tools in the dependency.

Can you upgrade to the latest enum-tools (0.12.0), or is there a conflict with another dependency? 0.10.0 and 0.11.0 also have the fix for this issue.
