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。
我的目录结构如下:
knife/
knife/
bin/
knife-cli.py
core/
main/
__init__.py
__init__.py
__init__.py
setup.py
我的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='author@email.com',
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,
)
我的knife/core/main/__init__.py
包含main()
个功能,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安装模块之后,我尝试运行knife-cli但继续抛出此错误:
$ 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'
真正发生了什么?我该如何解决呢?
答案 0 :(得分:5)
知道了,脚本正在执行旧的/usr/bin/knife.pyc
文件,我刚删除它,现在效果很好。

您还需要更多__init__
个。 __init__.py
文件告诉python该文件夹是python模块。您正在将这些作为模块重新设置在安装脚本中,因此您需要告诉python它们是模块。
knife/
knife/
bin/
knife-cli.py
core/
main/
__init__.py
__init__.py
__init__.py
setup.py
那应该解决主要问题。但是,您还要声明两个脚本,一个使用scripts
部分,另一个使用console_scripts
。控制台脚本实际上会为您创建脚本,因此您不需要在&#34; bin&#34;中包含您自己的脚本。
这是一个更好的setup.py给你:(注意我刚刚删除了脚本部分)
#!/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='author@email.com',
packages=find_packages(exclude=exclude),
include_package_data=True,
entry_points={
'console_scripts': [
'knife-cli = knife.core.main:main'
]
},
zip_safe=False,
)
