无法安装我自己的 PyPi 包：无法满足要求

Question

我正在尝试发布一个 PyPI 包。我通过先上传到 TestPyPI 来进行测试。我的 setup.py 相当简单：

import pathlib
from setuptools import setup, find_packages

# The directory containing this file
HERE = pathlib.Path(__file__).parent

# The text of the README file
README = (HERE / "README.md").read_text()

# This call to setup() does all the work
setup(
    name="my_package_name",
    version="0.0.1",
    description="My first Python package",
    long_description=README,
    long_description_content_type="text/markdown",
    url="https://github.com/my_package_url",
    author="John Smith",
    author_email="john.smith@gmail.com",
    license="MIT",
    classifiers=[
        "License :: OSI Approved :: MIT License",
        "Programming Language :: Python :: 3",
        "Programming Language :: Python :: 3.7",
    ],
    packages=find_packages(exclude=("test",)),
    include_package_data=True,
    install_requires=[
        "numpy",
        "scipy",
        "pandas",
        "statsmodels",
    ],
)

我正在关注 this tutorial。基本上，一旦 setup.py 准备好了，我运行

python3 setup.py sdist bdist_wheel

然后

twine upload --repository-url https://test.pypi.org/legacy/ dist/*

最后，为了实际测试我的包安装，我创建了一个新的虚拟环境并运行

pip install -i https://test.pypi.org/simple/ my_package_name

但是，我不断收到与 pandas 和 statsmodels 要求未得到满足相关的错误：

ERROR: Could not find a version that satisfies the requirement pandas (from my_package_name) (from versions: none)
ERROR: No matching distribution found for pandas (from my_package_name)

是不是因为 TestPyPI 没有那些包（不像 PyPI）？那么人们通常如何端到端地测试他们的软件包可以被其他用户顺利安装？

Answer 1

您只能有一个索引，但您可以有任意多个 extra indices。添加主 PyPI 作为额外索引：

pip install -i https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple/ my_package_name

首先 pip 查看索引，然后扫描额外的索引，直到找到包。
