python-3.x - 本地安装包-ImportError : module '__main__' has no attribute 'main'

Question

我需要一些关于 python 打包的帮助。我知道已经有人问过类似的问题，但我找不到解决我的问题的方法。

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)

__main__.py:

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

if __name__ == "__main__":
    main()

我做了以下事情:

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

不幸的是，我收到错误消息而不是“hello world”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'

谁能帮我展示我错过了什么？

我发现了问题:

在 setup.py 的 entry_points 中，我忘记输入 console_settings 的项目名称:

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