python点击setuptools集成问题

Question

我正在使用 python3.7.1 conda virtual env 遵循 python click 文档here 中的 setuptools 示例并继续收到错误：

ModuleNotFoundError: No module named 'yourpackage.scripts'

我一定遗漏了一些明显的东西，但不确定是什么。

yourpackage/
├── __init__.py
├── main.py
├── scripts
│   ├── __init__.py
│   └── yourscript.py
├── setup.py
└── utils.py

#scripts/yourscript.py
import click

@click.command()
def cli():
    """Example script."""
    click.echo('Hello World!')

# setup.py
from setuptools import setup, find_packages
setup(
    name='yourpackage',
    version='0.1',
    packages=find_packages(),
    include_package_data=True,
    install_requires=[
        'Click',
    ],
    entry_points='''
        [console_scripts]
        yourscript=yourpackage.scripts.yourscript:cli
    ''',
)

$ pip install -e .

ModuleNotFoundError: No module named 'yourpackage.scripts'

我还在我的包目录中尝试了以下内容： export PYTHONPATH=/tmp/yourpackage/ 并在运行yourscript时继续收到错误

Python 路径应包括包含yourpackage 的目录。在本例中为/tmp。

但是，更好的方法可能是重新排列源代码，以便在使用 setuptools 时无需调整 python 路径。像这样的：

yourpackage/
├── yourpackage/
|   ├── __init__.py
|   ├── main.py
|   ├── scripts
│   ├── __init__.py
│   ├── yourscript.py
|   └── utils.py
├── README.md
├── LICENSE
├── requirements.txt
└── setup.py

请参阅 github 上的 project，了解基于 click 的更大项目的示例。
