python - 使用外部 dowload_url 将包注册到 PyPi

Question

我正在尝试通过将包注册到 PyPI 并使用指向 bitbucket zip 文件的外部 download_url 来分发包。可以找到使用的安装文件 here .我使用

打包它

$ python setup.py sdist register

但是，pip 或 easy_install 找不到包

$ pip install PyBlockWork

download url在 https://pypi.python.org/pypi/PyBlockWork/0.1.0 上可用并正常运行但 pip 似乎只看 https://pypi.python.org/simple/PyBlockWork/其中不包含链接。我想 setup.py 文件中一定有问题，但我不知道是什么。

这个问题的长答案在于 PEP 438 .简短的回答是，通过 PyPi 分发 python 包正在重新定义中。默认情况下，新注册的包被置于 pip 不再访问“url”和“download_url”的模式。此外，链接不会自动添加到 https://pypi.python.org/simple/[package_name]/网页。要恢复到旧行为，可以登录他/她的 PyPi 帐户并在他/她的包的“url”选项卡中选择“如上所述，但也要求工具抓取主页和下载 URL(慢!)”作为托管模式.当然，这有很多含义，可以通过阅读一些关于这个主题的文章来理解。阅读PEP 438是一个很好的起点，但对于那些想要了解更多信息的人来说，here is also a good place to go .
