Yet another cross platform dependency bug

[corby]

Description

PySide6 released a MacOS ONY patch for 6.8.1.1
I'm on a linux machine (Ubunut)
My dependency is
pyside6 = '^6.8'

When dong a poetry update the update fails because it can't find a 6.8.1.1. patch for linux when it sees the mac file.

Workarround:

pyside6 = [
    { version = "^6.8.1.1", markers = "sys_platform == 'macos'" },
    { version = "6.8.1", markers = "sys_platform == 'win32'" },
    { version = "6.8.1", markers = "sys_platform == 'linux'" },
]

Example:

[build-system]
requires = ["poetry-core"]
build-backend = "poetry.core.masonry.api"

[tool.poetry]
name = "test"
version = "0.1.0"
description = ""
authors = [""]
readme = ""
packages = [
    { include = "test", from = "src" }
]

[tool.poetry.dependencies]
python = ">=3.10,<3.14"
pyside6 = "^6.8"
