Dummy dependency problem during install of ansible-lint

[la-magra]

• I have searched the issue tracker and this is definitely not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Context

This is a follow up to the following issues:

ansible/ansible-lint#2712 the thing that started it all

But most recent release v6.10.0 ansible/ansible-lint#2807 drops setup.cfg (finally...), but the problem remains.

ansible/ansible-lint#2816 the "pip works, we don't care about anything else".

python-poetry/poetry#7112 (comment) the poetry workaround

In short, ansible-lint decided to use a dummy/fake package (will-not-work-on-windows-try-from-wsl-instead; platform_system == "Windows") to stop installation on that unsupported platform.

edit. Feels related to #1535

Steps to reproduce

$ pdm --version
PDM, version 2.3.3

$ pdm init
...

$ pdm add -d 'ansible-lint'
Adding packages to dev dev-dependencies: ansible-lint
See /tmp/pdm-lock-7z2owtju.log for detailed debug log.
[CandidateNotFound]: Unable to find candidates for will-not-work-on-windows-try-from-wsl-instead. There may exist some issues with the package name or network condition.
Add '-v' to see the detailed traceback

Also trying the poetry workaround by adding the platform_system

#pyproject.toml
...
[tool.pdm]
[tool.pdm.dev-dependencies]
dev = [
    "ansible-lint<7.0.0,>=6.0.0; platform_system != \"Windows\"",
]
...

then running pdm install yields the same results.

Actual behavior

Package ansible-lint does not install.

Expected behavior

It unfortunately should, even with their horrendous dependency...

Add the following to pyproject.toml:

[tool.pdm.resolution.overrides]
will-not-work-on-windows-try-from-wsl-instead = "0.1.0"

[la-magra]

Wonderful, thank you.

[mledoze]

Thanks for the fix.

Unfortunately this does not work with Python 3.9 although ansible-lint requires Python >=3.8. It's because the dummy dependency will-not-work-on-windows-try-from-wsl-instead requires Python >=3.11. It does not make sense to me because this package has no code.

[la-magra]

Confirmed...

$ pdm update
�� Lock failed
Unable to find a resolution because the following dependencies don't work on all Python versions defined by the project's `requires-python`: >=3.9.
  python>=3.11,<4.0 (from <Candidate will-not-work-on-windows-try-from-wsl-instead@0.1.0 from https://pypi.org/simple/will-not-work-on-windows-try-from-wsl-instead/>)
To fix this, you can change the value of `requires-python` in pyproject.toml.

For some damned reason https://pypi.org/project/will-not-work-on-windows-try-from-wsl-instead/ is a yanked release AND defined a requires: Python >=3.11, <4.0
