Python 的 setup.py 安装的 CLI 脚本不允许导入相同的模块

我想创建一个名为 Knife 的 python 应用程序，可以从 CLI 执行，问题是它无法导入模块。我遵循与 Django 项目相同的文件夹结构以供参考。

我的目录结构是这样的：

knife/
    knife/
        bin/
            knife-cli.py
        core/
            main/
                __init__.py
            __init__.py
        __init__.py
    setup.py

My setup.py看起来像这样：

#!/usr/bin/env python

from setuptools import setup, find_packages

exclude = ['knife.bin']

setup(name='Knife',
      version='0.3',
      description='Very cool project',
      author='John Doe',
      author_email='[email protected] /cdn-cgi/l/email-protection',
      packages=find_packages(exclude=exclude),
      include_package_data=True,
      scripts=['knife/bin/knife-cli.py'],
      entry_points={
        'console_scripts': [
            'knife-cli = knife.core.main:main'
        ]
      },
      zip_safe=False,
     )

My knife/core/main/__init__.py包含一个main()功能和我的knife/bin/knife-cli.py看起来像这样：

#!/usr/bin/env python

from knife.core import main

if __name__ == "__main__":
    main.main()

因此，在使用 setup.py install 安装模块后，我尝试运行 Knife-cli 但不断抛出此错误：

$ knife-cli 
Traceback (most recent call last):
  File "/usr/bin/knife-cli", line 9, in <module>
    load_entry_point('Knife==0.3', 'console_scripts', 'knife-cli')()
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 468, in load_entry_point
    return get_distribution(dist).load_entry_point(group, name)
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2563, in load_entry_point
    return ep.load()
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 2254, in load
    ['__name__'])
  File "/usr/bin/knife.py", line 4, in <module>
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 646, in run_script
    self.require(requires)[0].run_script(script_name, ns)
  File "/usr/lib/python2.7/site-packages/pkg_resources.py", line 1559, in run_script
    raise ResolutionError("No script named %r" % script_name)
pkg_resources.ResolutionError: No script named 'knife.py'

到底发生了什么？我该如何解决这个问题？

明白了，脚本正在执行旧的/usr/bin/knife.pyc文件，我刚刚删除了它，现在运行良好。
