@YDBD What is your local version of pip? pip --version? Can you install the new pipenv that was just released 2022.8.5 -- I am curious if that works better for you or if you continue having this issue.

If you continue having this issue, I suspect it could be something unconventional in one of the setup.py that is being included as a dependency to your Pipfile.lock

[matteius]

@YDBD I believe your issue is related to use of string interpolation in the install_requires of the setup.py. Its not allowed by the parser because that is arbitrary callable code which we cannot execute safely. I think I can patch requirementslib to provide a better error in this case, there is another ticket about that: sarugaku/requirementslib#328
