Poetry doesn't install the correct dependency according to its supported Python version

• I am on the latest Poetry version.

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

• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: ubuntu 21.10

• Poetry version: 1.1.13

Issue

I have a wheel dependency on specific url for many platforms (Linuw/macOS/Windows) and many Python version (3.8, 3.9, 3.10).

Despite the fact I use Python 3.9, when I try poetry install, the python 3.8 version of the wheel is downloaded.

I also tried to:

• replace python = "^3.8" by python = "^3.9" (same thing);
• replace python = "~3.8", markers = "platform_system == 'Linux'", by markers = "python_version ~= '3.8' and platform_system == 'Linux'", (same thing).

Maybe related to #5378 or #5205, I don’t think it’s the same issue but I’m not sure.

Not to say that this isn’t a valid bug report

I don’t understand why this isn’t a valid bug report.

Apologies if my double-negative confused you. We are agreeing.

I see a similar problem with something like the following:

package = [
  { platform = "linux", python = "~3.7.0", url = "https://some.url.com/path/to/package-cp37-cp37-linux_x86_64.whl" },
  { platform = "linux", python = "~3.8.0", url = "https://some.url.com/path/to/package-cp38-cp38-linux_x86_64.whl" },
  { platform = "linux", python = "~3.9.0", url = "https://some.url.com/path/to/package-cp39-cp39-linux_x86_64.whl" },
  { platform = "darwin", python = "~3.7.0", url = "https://some.url.com/path/to/package-cp37-cp37-macosx_10_14_x86_64.whl" },
  { platform = "darwin", python = "~3.8.0", url = "https://some.url.com/path/to/package-cp38-cp38-macosx_10_14_x86_64.whl" },
  { platform = "darwin", python = "~3.9.0", url = "https://some.url.com/path/to/package-cp39-cp39-macosx_10_14_x86_64.whl" },
]

In this case, poetry attempts to install only the first URL–if I look at poetry.lock, I see something like

[[package]]
name = "package"
version = "1.2.3"
description = ""
category = "main"
optional = false
python-versions = "*"

[package.source]
type = "url"
url = "https://some.url.com/path/to/package-cp37-cp37-linux_x86_64.whl"

So, poetry only stores a single URL in the lock file, despite there being multiple URLs specified in pyproject.toml

EDIT: The python versions above were incorrect (i.e., previously, it had "~3.7", but it should have been "~3.7.0"). I’ve fixed it now. Unfortunately, that doesn’t fix the behavior.
