Root Cause

Pip receives an empty or non-JSON response from a package index, often due to network issues or misconfigured index URL.

generic

中文

pip 从包索引收到空响应或非 JSON 响应，通常是由于网络问题或索引 URL 配置错误。

Workarounds

  1. 90% success Check the index URL for correctness 
    Run: pip install -i https://pypi.org/simple/ package (ensure URL ends with /simple)
  2. 85% success Use a different index or mirror 
    Run: pip install -i https://pypi.tuna.tsinghua.edu.cn/simple package

Dead Ends

Common approaches that don't work:

  1. Retrying with the same index URL 90% fail

    The index URL may be broken; retries won't fix it.

  2. Using a different HTTP method like POST 80% fail

    Pip uses GET; changing method is not supported.
