Description
The following dockerfile is the minimum reproducible example of a situation I met in a real project CI.
The Dockerfile runs with python 3.10 but there is a setuptools dependency for python 3.12+ in pyproject.toml.
The other dependency in pyproject.toml is pycountry, on its 22.1.10 version, and it has a loose dependency to setuptools.
In this situation I would expect setuptools to not be a direct dependency. However uv --resolution=lowest-direct appears to resolve at the minimum setuptools available, that is 0.7.2. Of course, this is an old incompatible version, and the installation fails.
Removing the python_version>='3.12' constraint on the setuptools dependency appears to solve the issue, so I suppose this is a cause of the bug.
