Python package "click" causes "Error: Got unexpected extra arguments (sdist bdist_wheel)" when used in new package

Question

我正在尝试创建一个可以用作终端命令的 Python 包。我的 setup.py 文件看起来像

import setuptools

# If the package is being updated (and not installed for the first time),
# save user-defined data.
try:
    import checklist
    update = True
except ModuleNotFoundError:
    update = False

if update:
    import os
    import pickle
    dir = os.path.join(os.path.dirname(checklist.__file__), 'user_settings')
    files = {}
    for file in os.listdir(dir):
        files[file] = pickle.load(open(os.path.join(dir, file), "rb"))

with open("README.md", "r") as fh:
    long_description = fh.read()

setuptools.setup(
    name="SampleName",
    version="0.2.0",
    author="Author1, Author2",
    author_email="email@email.com",
    description="words words words.",
    long_description=long_description,
    long_description_content_type="text/markdown",
    url="https://github.com/samplesample/sample1",
    packages=setuptools.find_packages(),
    classifiers=[
        "Programming Language :: Python :: 3",
        "License :: OSI Approved :: GNU General Public License v3 (GPLv3)",
        "Operating System :: OS Independent",
    ],
    entry_points='''
        [console_scripts]
        checklist=checklist.checklist:cli
    ''',
    python_requires='>=3.7',
    package_data={"checklist":["user_settings/*.pkl"]},
    include_package_data=True,
)

if update:
    for key in files:
        pickle.dump(files[key], open(os.path.join(dir, key), "wb"))

当我尝试使用命令

创建 checklist 包时

python setup.py sdist bdist_wheel

我收到消息

Error: Got unexpected extra arguments (sdist bdist_wheel)

当我从我的环境中删除 click 时，轮子的创建没有问题。这看起来很奇怪，因为我的代码使用 click.

import os
import sys
import csv
import click
import datetime as dt
from datetime import datetime
from contextlib import suppress
import pickle


class UI:

    def __init__(self):
        <set variables>...

    <some methods>...

# noinspection SpellCheckingInspection
class Checklist(UI):

    def __init__(self):
        <set variables>...

        # start the process...
        while self.step_index < len(self.to_do):
            with suppress(ExitException):
                self.step()

    def step(self):
        self.__getattribute__(self.to_do[self.step_index])()
        self.step_index += 1
        self.overwrite = False

    <some methods>...


@click.command()
def cli():
    Checklist()

cli()

这可能是什么原因造成的？我该如何解决？

令人惊讶的是，与最佳实践的一些小偏差如何链接在一起产生一个大问题。 :-)

click 的问题如下。如果安装了 click，您的 setup.py 将导入您在上面向我们展示的模块。并且模块 在导入时 运行s cli()，表示 cli() 调用 @click.command() 并解析命令行（用于 setup.py，不适用于 click) 并产生错误。

如果未安装 click，您的 setup.py 会尝试导入 checklist，但失败 ModuleNotFoundError。在 setup.py 中捕获并忽略了异常并继续安装。

为了解决这个问题，使 checklist 成为一个既可以是运行（调用 cli()）又可以在不调用 cli() 的情况下导入的模块：

def main():
    cli()

if __name__ == '__main__':
    main()
