本地安装的package-ImportError：module＆＃39; __ main __＆＃39;没有属性＆＃39; main＆＃39;

Question

我需要一些python包装的帮助。我已经知道类似的问题了，但我找不到解决问题的方法。

这是树的输出：

.
├── env
├── prala
│   ├── __init__.py
│   └── __main__.py
└── setup.py

setup.py ：

from setuptools import setup, find_packages
setup(
      name='prala',
      version='0.5',
      description='Practice Language',
      url='http://github.com/*/*',
      author='*',
      author_email='*@*.com',
      license='MIT',
      classifiers =[
        "Programming Language :: Python",
        "Programming Language :: Python :: 3",
      ],

      packages=find_packages(),
      entry_points = {
        'console_scripts': ['ppp=__main__:main'],
      },
      zip_safe=False)

__主__吡啶：

def main():
   print("hello world")

if __name__ == "__main__":
    main()

我做了以下事情：

1. 我在root中激活了virtualenv：$ source env/bin/activate
2. 我构建了dist并安装了它：(env) $ python setup.py install
3. 我运行了入口点：(env) $ ppp

不幸的是我得到了错误，而不是'＃hello world＆＃39;消息：

Traceback (most recent call last):
  File "/home/akoel/Projects/python/delete/env/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2332, in resolve
    return functools.reduce(getattr, self.attrs, module)
AttributeError: module '__main__' has no attribute 'main'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/home/akoel/Projects/python/delete/env/bin/ppp", line 11, in <module>
    load_entry_point('prala==0.5', 'console_scripts', 'ppp')()
  File "/home/akoel/Projects/python/delete/env/lib/python3.6/site-packages/pkg_resources/__init__.py", line 480, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/home/akoel/Projects/python/delete/env/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2693, in load_entry_point
    return ep.load()
  File "/home/akoel/Projects/python/delete/env/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2324, in load
    return self.resolve()
  File "/home/akoel/Projects/python/delete/env/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2334, in resolve
    raise ImportError(str(exc))
ImportError: module '__main__' has no attribute 'main'

任何人都可以帮助我展示我错过的内容吗？

我发现了问题：

在 setup.py 的 entry_points 中，我忘了为 console_settings 设置项目名称：

  entry_points = {
    'console_scripts': ['ppp=prala.__main__:main'],
  },
