Error when installing my project with path = "." in [tool.pixi.pypi-dependencies] on Windows (works fine on mac)

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

Run pixi shell (with pixi 0.39.0) on Windows with the following pyproject.toml

[project]
name = "joe"
version = "0.3.9"
requires-python = "==3.10.8"

[tool.pixi.project]
channels = ["conda-forge"]
platforms = ["win-64"]

[tool.pixi.pypi-dependencies]
joe = { path = ".", editable = true }

Issue description

I get the following error when installing the above project on Windows :

WARN win-arm64 is not supported by the pixi.toml, falling back to win-64 (emulation)
  × failed to solve the pypi requirements of 'default' 'win-64'                                                                                                                   
  ├─▶ failed to resolve pypi dependencies                                                                                                                                         
  ╰─▶ Because the requested Python version (==3.10.*) does not satisfy Python==3.10.8 and joe==0.3.9 depends on Python==3.10.8, we can conclude that joe==0.3.9 cannot be used.   
      And because only joe==0.3.9 is available and you require joe, we can conclude that your requirements are unsatisfiable.                                                     

      hint: The `requires-python` value (==3.10.*) includes Python versions that are not supported by your dependencies (e.g., joe==0.3.9 only supports ==3.10.8). Consider       
      using a more restrictive `requires-python` value (like ==3.10.8).

I tried on Windows 10 and 11. I don't have the problem on OS X (just add "osx" in platforms).

Expected behavior

It should be able to install my project.

When I remove joe = { path = ".", editable = true } from [tool.pixi.pypi-dependencies], pixi manages to install the project on Windows:

[project]
name = "joe"
version = "0.3.9"
requires-python = "==3.10.8"

[tool.pixi.project]
channels = ["conda-forge"]
platforms = ["win-64"]

Any idea why?

[arthursw]

Actually, it also works when I keep editable = true, like in the following:

[project]
name = "joe"
version = "0.3.9"
requires-python = "==3.10.8"

[tool.pixi.project]
channels = ["conda-forge"]
platforms = ["win-64"]

[tool.pixi.pypi-dependencies]
joe = { editable = true }

So the problem comes from path = ".".

Any idea why?

This line seems weird to me:

Python version (==3.10.*) does not satisfy Python==3.10.8

It works when I make the requires-python = "==3.10.*", this looks like a bug. @tdejager I can't find a reason why it would error on this, also not in the uv code. Do you have any idea?

[tdejager]

Yeah, so it apparently has to do with the Python requirment we are setting for the solver

We specifically set it to a 3.10.* version in this case, which might select a different version then the constraint on the patch version. We could try making this requirement as narrow as possible, and see if that works.

This problems also occurs on macOS when I've tested it.

Thanks for testing 👍
Strange, on my osx-arm64 I could install the project successfully with pixi 0.26.1.
