[BUG] stderr duplication failed

setuptools version

setuptools==56.0.0

Python version

Python 3.9

OS

Windows

Additional environment information

No response

Description

I use gui_scripts with a blank function. If i use pip install -e . or py setup.py install nothing happens, as expected. If i do pip install . or use setup.py to make a binary dist then install it, i get stderr duplication failed in a prompt. This happens before any code gets run.

Expected behavior

Nothing

How to Reproduce

# setup.py
from setuptools import setup

setup(
    name="test",
    packages=["test"],
    entry_points={
        "gui_scripts": [
            "test-script=test:main"
        ]
    }
)

# test/__init__.py
def main():
    pass

Run above commands

Just waiting for a response from @rayzchen (and anyone else) and then I should be able to cut a release soon after that.

Thanks @cbrnr and @carlkl for redoing the tests. Looking promising 🤞
