根因分析

pip 无法验证 SSL 证书，因为证书链包含自签名证书，通常是由于企业代理或防病毒软件。

English

pip cannot verify the SSL certificate because the certificate chain includes a self-signed certificate, often due to a corporate proxy or antivirus software.

解决方案

  1. 90% 成功率 
    pip install --cert /path/to/corporate-ca.pem package
  2. 85% 成功率 
    pip install --upgrade certifi; export SSL_CERT_FILE=$(python -m certifi)

无效尝试

常见但无效的做法:

  1. 50% 失败

    Disables SSL verification, exposing you to MITM attacks; not a proper fix.

  2. 60% 失败

    Globally disables HTTPS verification for Python, affecting all libraries; insecure.
