在setuptools中将目录模块添加到py_modules中

如何解决在setuptools中将目录模块添加到py_modules中

我可能又犯了一个愚蠢的错误。但是我找不到它。即使在这个极小的最小（不是）工作示例中……

文件夹结构：

setup.py
x_module
    __init__.py
    main.py

setup.py包含

from setuptools import setup

setup(
    name= 'setup-test',version='0.1',py_modules = ['x_module' ],entry_points = '''
        [console_scripts]
        x_test=x_module.main:main
    '''
)

__init__.py为空

main.py包含

#!/usr/bin/env python3

def main():
    print('x_module.main.main() executed')

命令行输出：

$ pip install .

奇怪的是它在可编辑模式下工作：

$ pip install -e .
