[BUG] pyproject.toml doesn't always install all entry points, but setup.py does

setuptools version

67.4.0

Python version

python 3.10.10

OS

Windows

Additional environment information

I've got a large command line set that I use across platforms called zcmds

Recently I noticed that the root command zcmds which is designed to print out all commands, was missing. Looking at the **/Scripts directory I see that some of the executables are installed, some of them are not.

Description

I was able to resolve it by folding pyproject.toml into the setup.py file. Now everything works!

This is the broken version:
https://github.com/zackees/zcmds/commit/04e85af5504a7cbc829dd727d7c2a468f75a07e9

And this works:
https://github.com/zackees/zcmds/commit/2c9b19561b5ddf93cd302571e010cf22cabac478

The difference between these two change lists is folding pyproject.toml into setup.py and the deletion of pyproject.toml

Expected behavior

I expect the zcmds toolset and all exe's to be generated.

How to Reproduce

git clone https://github.com/zackees/zcmds
cd zcmds
pip install -e .
zcmds

You should see

    git-bash
    grep
    home
    ls
    mv
    open
    rm
    sudo
    touch
    which

Instead there is a file not found error.

Output

Note that yes, I did remove python 3.10 and did a fresh re-install and the problem still persisted.

If you want to use my exact copy of python 3.10 then use this installer that I've saved to my github:

https://github.com/zackees/python3.10.

You can also use this script at the Win command terminal which will install python 3.10 and add it to the path.

powershell -Command "Invoke-WebRequest -Uri 'https://raw.githubusercontent.com/zackees/python3.10/main/winpyinstall310.bat' -OutFile 'winpyinstall310.bat'; .\winpyinstall310.bat"

Start by comparing the linked broken and working revisions, especially pyproject.toml and setup.py, then reproduce the editable install with Python 3.10 on Windows using pip install -e .. Check how setuptools discovers the entry points and verify that the expected zcmds executable set is generated without the file-not-found error.
