Hello everyone,

enum_tools version: 0.6.5

After updating Sphinx version from 4.2.0 to 4.3.1, I encounter this issue:

AttributeError: can't set attribute

With same version of enum_tools (0.6.5), I got this error with sphinx 4.3.0 and 4.3.1 but not with 4.2.0

[domdfcoding]

Sorry about this. enum_tools hadn't been updated to account for changes made in 3.5 and later. #48 should resolve this

@garf365 @1kastner can you try that branch with Sphinx 4.3 and let me know if it works for you?

You can install the branch with pip install git+https://github.com/domdfcoding/enum_tools@sphinx4

[calebstewart]

I'm not the original author of this issue, but I had the same issue, and the branch does fix the problem for me 👍

[1kastner]

Everything looks good to me!

[domdfcoding]

Thanks both for your feedback. I will merge the PR and make a release.

[domdfcoding]

I've released version 0.7.0 with support for Sphinx 4.x

[garf365]

Thank you !
