问题描述

我正在尝试发布一个 PyPI 包。我首先上传到TestPyPI进行测试。我setup.py的很简单:

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",
    ],
)

我正在关注本教程。基本上,一旦setup.py准备好,我就跑

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,我不断收到与不满足要求相关的pandas错误statsmodels

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)

是因为 TestPyPI 没有那些包(不像 PyPI)吗?那么人们通常如何端到端测试他们的包可以被其他用户顺利安装呢?

解决方案


您只能拥有一个索引,但您可以拥有任意数量的额外索引。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。
