Root Cause

The extra index URL is using HTTP instead of HTTPS, or SSL configuration is incorrect.

generic

中文

额外的索引 URL 使用了 HTTP 而不是 HTTPS，或 SSL 配置不正确。

Workarounds

  1. 90% success Use HTTPS for the index URL 
    pip install --extra-index-url https://example.com/simple package_name
  2. 70% success Check SSL certificates and update 
    Update CA certificates on system

Dead Ends

Common approaches that don't work:

  1. Increasing retries 40% fail

    Doesn't fix the underlying SSL issue.

  2. Disabling SSL verification 30% fail

    Security risk.
