Why does "eggsecutable" search for main

I try to make a executable *.egg file. I can create this using the following method: I just put a __main__.py at the top-level of an .egg named .zip, and python will run that __main__.py

I have read that there is a more elegant way:

setup(
    # other arguments here...
    entry_points={
        'setuptools.installation': [
            'eggsecutable = my_package.some_module:main_func',
        ]
    }
)

https://setuptools.readthedocs.io/en/latest/setuptools.html#eggsecutable-scripts

But if I create ( with run setup.py bdist_egg) and run the *.egg, it prints: C:\Python27\python.exe: can't find '__main__' module in <eggpath>

So python doesn't find the entry point.

Is it possible make an executable egg without explicit __main__.py?

System:

Win 7
Python 2.7.9
setuptools 39.0.1 from c:\python27\lib\site-packages (Python 2.7))

UPDATE

I have tried both on Linux both with python3 and I got the same error.

Solution

It seems like the entry points documentation is misleading and you don't need them.

What you probably want something like this:

setup.py:

import setuptools

setuptools.setup(
    name="example_pkg",
    version="0.0.1",
    # all the other parameters

    # function to call on $ python my.egg
    py_modules=['example_pkg.stuff:main']
)

example_pkg/stuff.py

def main():
    print("egg test")

if __name__ == '__main__':
    main()

create the egg: setup.py bdist_egg

run the egg: python dist\example_pkg-0.0.1-py3.6.egg

output: egg test
