解决方案

  1. 90% 成功率 Use a mirror or alternative index 
    pip install package -i https://pypi.douban.com/simple/
  2. 85% 成功率 Configure proxy if behind firewall 
    pip install package --proxy http://user:pass@proxy:port

无效尝试

常见但无效的做法:

  1. Increasing pip timeout with --timeout=100 70% 失败

    Timeout extension doesn't fix underlying network connectivity.

  2. Using --no-cache-dir 80% 失败

    Cache is not the issue; network still unreachable.
