python - 构建 python pypi 轮子，通常的噩梦

Question

我正在尝试构建一个包并将其上传到 pypi ，我已经过了这一 pip 并且上传成功，让我引导您完成我正在做的事情:

setup.py :

from setuptools import setup, find_packages

setup(
    name='project_name',
    version='1.0',
    packages=find_packages(),
    url='url',
    license='license',
    author='author',
    author_email='email_here@some_mail.com',
    description='description',
    install_requires=[
        'oauth2client',
        'pyarrow',
        'pandas',
        'requests',
        'gcloud'
    ],
)

我愿意:

% python3 setup.py sdist bdist_wheel

随后

% python3 -m twine upload -u username -p password --repository-url https://test.pypi.org/legacy/ dist/*

两者都运行得很好，没有错误/警告......

然后我得到一个网址，其中包含:

% pip install -i https://test.pypi.org/simple/ project_name==1.0

所以我创建了一个 virtualenv环境并尝试安装:

% virtualenv test_env
% source test_env/bin/activate
% pip install -i https://test.pypi.org/simple/ project_name==1.0

出于某种原因，我首先得到这个:

ERROR: Could not find a version that satisfies the requirement gcloud (from project_name==1.0) (from versions: none)
ERROR: No matching distribution found for gcloud (from project_name==1.0)

然后，在重试(未应用任何更改)运行最后一个命令后，我得到了其他结果，并且还得到了其他结果。那么...出了什么问题？

注意: 该软件包很好，我可以将其安装在我的 mbp 的系统解释器 (python3.8) 上，但这是因为所有依赖项 numpy , gcloud ...已经安装。

Answer 1

我认为这是因为 pip 正在 https://test.pypi.org/simple/ 中寻找不存在的包依赖项。

尝试:

pip install --index-url https://test.pypi.org/simple/ --extra-index-url https://pypi.org/simple your-package

这将从 test.pypi 中提取您的包，但当 pip 无法找到其中的依赖项时，会退回到常规 pypi。
