pre-commit failing on mypy hook with at least a 'Module has no attribute "getuid" error'

[WarrenTheRabbit]

description of problem

On VS Code, I am attempting to commit a staged change of src\_pytest\config\__init__.py; however, the pre-commit hook fails on mypy with command ouput:

mypy.....................................................................Failed
- hook id: mypy
- exit code: 1

src\_pytest\compat.py:324: error: Module has no attribute "getuid"; maybe "getpid" or "getppid"?  [attr-defined]
Found 1 error in 1 file (checked 1 source file)

Every other hook either passes or is skipped. I installed pre-commit and its hook on the pytest repo using

$ pip install --user pre-commit
$ pre-commit install

pip list output

minimal example

If I discard my changes and do pre-commit run --all-files, everything passes or is skipped except for

mypy.....................................................................Failed
- hook id: mypy
- exit code: 1

src\_pytest\compat.py:324: error: Module has no attribute "getuid"; maybe "getpid" or "getppid"?  [attr-defined]
testing\test_parseopt.py:294: error: Module has no attribute "getencoding"  [attr-defined]
Found 2 errors in 2 files (checked 224 source files)

[WarrenTheRabbit]

I've noticed # type ignore[something] in the pytest repo.
Would it be reasonable to do a pull request that adds # type: ignore[attr-defined] to the two lines that fail the mypy hook, and to link it as a fix for this issue?

src\_pytest\compat.py:324: error: Module has no attribute "getuid"; maybe "getpid" or "getppid"?  [attr-defined]
testing\test_parseopt.py:294: error: Module has no attribute "getencoding"  [attr-defined]

I can confirm that the mypy hook passes after adding #type: ignore[attr-defined] lines at those locations.
