根因分析

由于系统缺少或CA证书过期，SSL证书验证失败。

English

SSL certificate verification fails due to missing or outdated CA certificates on the system.

generic

解决方案

  1. 90% 成功率 Update CA certificates 
    pip install --upgrade certifi
# Or system level: sudo update-ca-certificates
  2. 85% 成功率 Use a custom CA bundle if behind corporate proxy 
    pip install --cert /path/to/custom-ca-bundle.crt package

无效尝试

常见但无效的做法:

  1. Disabling SSL verification with --trusted-host 30% 失败

    Security risk; may work but exposes to man-in-the-middle attacks.

  2. Using --cert with wrong path 70% 失败

    Path to certificate may be incorrect or file missing.
