Locking fails with ModuleNotFoundError for distutils

[GPHemsley-RELX]

Possibly related:

• pipenv install errors out with ModuleNotFoundError: No module named 'distutils.cmd' even though it is present on the system #5674
• Support for Python(s) (3.10+?) without distutils. #6125

Trying to update from Python 3.11 to 3.12. Created a new pipenv environment using a new pyenv version installation.

Python 3.12.9
pip 24.3.1
pipenv 2024.4.1

Trying to run pipenv lock results in an error of "metadata generation failed".

Trying to run pipenv run pip install pipenv (or any other package) results in:

Traceback (most recent call last):
  File "/.../bin/pip", line 5, in <module>
    from pip._internal.cli.main import main
  File "/.../lib/python3.12/site-packages/pip/_internal/cli/main.py", line 10, in <module>
    from pip._internal.cli.autocompletion import autocomplete

  File "/.../lib/python3.12/site-packages/pip/_internal/cli/cmdoptions.py", line 19, in <module>
    from distutils.util import strtobool
ModuleNotFoundError: No module named 'distutils'

Running import distutils within the interactive interpreter results in the same error within the virtual environment, but works as expected after exiting the virtual environment.

It seems this is somehow related to having access-parser = "*" in the Pipfile. This library is currently at version 0.0.6; I don't know if <1.0 is messing with the calculation, but adding --pre doesn't change anything. Removing that requirement from the Pipfile allows pipenv lock to work, but not pipenv run pip install pipenv.
