根因分析

pip 无法验证包索引的 SSL 证书，通常是由于缺少 CA 证书、企业代理拦截或 certifi 包过时。

English

pip cannot verify the SSL certificate of the package index, often due to missing CA certificates, corporate proxy interception, or outdated certifi bundle.

generic

解决方案

  1. 80% 成功率 
    pip install --upgrade certifi
  2. 90% 成功率 
    sudo apt-get install ca-certificates && sudo update-ca-certificates
  3. 85% 成功率 
    pip install --cert /path/to/corporate-ca-bundle.crt package

无效尝试

常见但无效的做法:

  1. 60% 失败

    This bypasses security and may still fail if the proxy requires a specific CA.

  2. 95% 失败

    Reinstalling Python does not fix missing or outdated CA certificates.

  3. 90% 失败

    PyPI redirects HTTP to HTTPS; the SSL error persists.
