构建python pypi轮子，通常的噩梦

问题描述

我正在尝试构建一个程序包并将其上传到pypi，我越过了这一点，上传成功了，让我向您介绍我在做什么：

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

其次是

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

两者运行都很好，没有错误/警告...

然后我得到一个包含以下内容的网址：

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

因此，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，我首先得到了这个信息：

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）以运行最后一个命令后，我得到了其他东西，我也得到了其他结果。那...怎么了？

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，{ {1}} ...已安装。

解决方法

我认为这是因为pip在https://test.pypi.org/simple/中寻找不存在的程序包相关性。

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中提取您的包裹，但是当pip无法在其中找到依赖项时，便退回常规pypi。
