python - 从哪些存储库安装 pip 包？

问题描述

我需要使用 pip 下载一个包。我跑pip install <package>了，但出现以下错误：

[user@server ~]$ pip install sistr_cmd
Collecting sistr_cmd
  Retrying (Retry(total=4, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError('<pip._vendor.requests.packages.urllib3.connection.

  Could not find a version that satisfies the requirement sistr_cmd (from versions: )
No matching distribution found for sistr_cmd

我确认问题的根源是网络阻止了大多数站点，因为我在代理后面工作（组织要求）。为了允许这些下载，我需要编译下载源的 url 列表并将其发送给网络管理员以解除阻止。

根据 pip 文档（在 pip Wikipedia 文章中简要引用和解释），“许多包可以在包及其依赖项的默认源 - Python 包索引 (PyPI) 中找到”，所以我去了 Biopython 的 PyPI 页面并找到了 github 存储库和包所需的依赖项。PyPI 页面上还有下载链接，我想确保所有下载源都被允许。pip 从包的原始源安装也是如此（ github 存储库或托管原始包的任何地方），下载中列出的 PyPI 页面中的包，还是搜索两者？

预先感谢您的帮助。
