Inspecting the wheel, we can see there isn’t the ruamel package.

Expected result

pipenv check works as expected.

@yeisonvargasf adding an init file would get blown away during revendoring unless it was created via the patch, so I like this way for now.

I merged a small change to setup.py to main that worked locally to include ruamel in the wheel. Feel free to try it out @yeisonvargasf – I plan to do a follow-up release 2022.11.24 either later tonight or tomorrow.
