尝试创建应作为命令行脚本使用的自定义包时出现ModuleNotFoundError

Question

我希望能够执行trump并使用rest api获得随机报价
注意：在王牌之前没有python

我有以下目录结构-

trump  
|--setup.py  
|--trump  
|-- quote.py
|-- __init__.py
|-- __main__.py

setup.py包含-

from setuptools import setup, find_packages
import sys
if sys.version_info[0] != 3:
raise RuntimeError('Unsupported python version "{0}"'.format(sys.version_info[0]))
setup(name='trump',
version='0.1',
description='Trumps tweets',
keywords=['trump'],
#include_package_data=True,
packages=find_packages('trump'),
package_dir={'':'trump'},
license='GNU GPL v3',
python_requires="!=3.0.*, !=3.1.*, !=3.2.*, !=3.3.*",
install_requires=[
'requests',
],
entry_points = {
'console_scripts': [
'trump = trump.__main__:main'
]
},
zip_safe=False
)

__init__.py为空
__main__.py包含-

import quote
def main():
quote.vomit()
if __name__=='__main__':
main() 

并且quote.py包含-

import requests
def vomit():
api_response = requests.get('http://api.tronalddump.io/random/quote')
quote = api_response.json()['value']
print(quote)

在根目录中，当我运行python3 trump时，我会得到正确的结果。然而，当我通过pip将其安装为pip3 install --user -e .，然后尝试执行trump时，我会得到以下错误-

$ trump
Traceback (most recent call last):
File "/home/walker/.local/bin/trump", line 11, in <module>
load_entry_point('trump', 'console_scripts', 'trump')()
File "/home/walker/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 487, in load_entry_point
return get_distribution(dist).load_entry_point(group, name)

return ep.load()

return self.resolve()
File "/home/walker/.local/lib/python3.6/site-packages/pkg_resources/__init__.py", line 2352, in resolve
module = __import__(self.module_name, fromlist=['__name__'], level=0)
ModuleNotFoundError: No module named 'trump'

我尝试过遵循python打包文档，但似乎不明白为什么会发生这种情况。

编辑：
执行packages=find_packages()后，我得到以下错误-

$ pip install --user -e .
Obtaining file:///trump
Complete output from command python setup.py egg_info:

----------------------------------------
Command "python setup.py egg_info" failed with error code 1 in /trump/

这让我相信我对package_dir和packages的配置是错误的。但问题是，如果我评论package_dir行，并且在package(具有trump或空(的任何一种情况下，我都会得到以下响应-

$ trump
bash: trump: command not found

Answer 1

从packages=find_packages('trump')中删除'trump'。'trump'是要包含在分发中的包，而find_packages('trump')在trump/目录中查找，在那里找不到任何包，并返回一个空列表。

packages=find_packages()

此外，您根本不需要package_dir。它将用于在src/中有trump/子目录的情况，因此您将使用

package_dir=｛''：'src'｝，
