Poetry tries to install url dependency with platform='linux' on macOS

[kjyv]

• Poetry version: 1.5.1

• Python version: 3.11.3

• OS version and name: macOS 13.4

• I am on the latest stable Poetry version, installed using a recommended method.

• I have searched the issues of this repo and believe that this is not a duplicate.

Issue

I'm trying to install torch differently for darwin and linux. macOS should come from pypi, linux should come from a url.
My pyproject.toml entry is this:

torch = [
        {platform = "darwin", version = "==2.0.0"},
        {platform = "linux", markers = "sys_platform == 'linux' and platform_machine == 'x86_64'", url = "https://download.pytorch.org/whl/cpu/torch-2.0.0%2Bcpu-cp311-cp311-linux_x86_64.whl"}
]

(previously tried it with variations of platform_system, only using the platform argument, all behave the same though)

Locking works and adds hashes to the lock file. However upon install on macOS, poetry tries to install the linux wheel and this exception is generated:

 • Installing mpmath (1.3.0)
  • Installing networkx (3.1)
  • Installing sympy (1.12)
  • Installing torch (2.0.0+cpu https://download.pytorch.org/whl/cpu/torch-2.0.0%2Bcpu-cp311-cp311-linux_x86_64.whl): Failed

I have seen that there are multiple torch related tickets, but these seem to discuss other issues and also, this does not seem to be specific to torch, poetry should not even try to install the wheel on macOS.

You have to specify source = "PyPI" for your first constraint, otherwise the constraints will be merged because the first one can be satisfied by the second one.

I see, thanks and sorry for the unnecessary ticket. I guess it's not very intuitive that it has to be done like this. And I did try with both lines, respectively, using a custom source for torch and one with source="pypi" that apparently failed for other reasons (already being discussed in the torch issues)
