Specifying a python sub-version causes dependency resolution to fail #5205
Description
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
Commands I ran and their output:
$ pixi init --format pyproject
✔ Created /Users/d9i/Documents/Projects/pixitest/pyproject.toml
# Modify the pyproject.toml to specify `requires-python = "== 3.10.6"`
$ pixi install
Error: × failed to solve the pypi requirements of environment 'default' for platform 'osx-arm64'
├─▶ failed to resolve pypi dependencies
╰─▶ Because the requested Python version (==3.10.*) does not satisfy Python==3.10.6 and pixitest==0.1.0 depends on Python==3.10.6, we can conclude that
pixitest==0.1.0 cannot be used.
And because only pixitest==0.1.0 is available and you require pixitest, 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., pixitest==0.1.0 only supports
==3.10.6). Consider using a more restrictive `requires-python` value (like ==3.10.6).pixi.toml/pyproject.toml file that reproduces my issue:
[project]
authors = [{name = "my name", email = "my_email@gmail.com"}]
dependencies = []
name = "pixitest"
requires-python = "== 3.10.6"
version = "0.1.0"
[build-system]
build-backend = "hatchling.build"
requires = ["hatchling"]
[tool.pixi.workspace]
channels = ["conda-forge"]
platforms = ["osx-arm64"]
[tool.pixi.pypi-dependencies]
pixitest = { path = ".", editable = true }
[tool.pixi.tasks]
pixi info output:

Issue description
If I specify a requires-python value with more than one period in it, dependency resolution will fail. For some reason, pixi thinks my value is "== 3.10.*" but I have specified "== 3.10.6" -- might be some kind of mixup between pixi and uv? Or I could just be using the tool wrong.
Expected behavior
Successful environment build using the specified python version (3.10.6)
