Pip v22 breaks pre-commit on Windows

[john-adamson]

Description

Pre-commit no longer works on Windows when using Pip v22

Expected behavior

If pre-commit is installed it should be able to add a Git hook to the .git/hooks folder.
Additionally, running the pre-commit command should produce output.

pip version

22

Python version

3.10

OS

Windows 10

How to Reproduce

1. Install Python 3.10 and Git (including Git Bash) on Windows 10
2. Open Git Bash
3. Run:

$ mkdir precommittest
$ cd precommittest
$ <path to installed python exe> -m venv venv
$ . ./venv/Scripts/activate
$ python -m pip install pip --upgrade
$ python -m pip install pre-commit
$ pre-commit sample-config > .pre-commit-config.yaml
$ pre-commit install
$ pre-commit run --all-files

The final two lines will do nothing with Pip v22.

If the python -m pip install pip --upgrade step is skipped then pre-commit will work as expected.

Output

There will be no output using Pip v22 (but there should be).

Please report to pre-commit for the issue. pip maintainers don’t understand how pre-commit install works and can’t provide meaningful support without input from pre-commit. Feel free to report back and reopen if pre-commit identifies more information on how the issue related to pip.

This is likely #10875 on our end.

Note that for an existing .pre-commit-config.yaml (rather than the example given above) the pre-commit install doesn't even copy to .git/hooks
