根因分析

pip 配置了一个在当前网络上无法访问的额外索引 URL，导致在回退前反复重试。

English

pip is configured with an extra index URL that is unreachable from the current network, causing retries before falling back.

解决方案

  1. 90% 成功率 
    pip config unset global.extra-index-url  # or edit ~/.config/pip/pip.conf
  2. 85% 成功率 
    pip install --index-url https://pypi.org/simple <package>

无效尝试

常见但无效的做法:

  1. 90% 失败

    More retries just delay the same connection failure.

  2. 95% 失败

    The connection is refused immediately; timeout is not the issue.

  3. 90% 失败

    pip itself is fine; the configured index URL is the problem.
