Root Cause

pip's HTTP cache or wheel cache contains a corrupted download, often due to interrupted network transfer or disk write errors. pip attempts to read the cached file as a zip archive but fails.

generic

中文

pip 的 HTTP 缓存或 wheel 缓存中包含损坏的下载文件，通常是由于网络传输中断或磁盘写入错误导致。pip 尝试将缓存文件作为 zip 归档读取时失败。

Workarounds

  1. 95% success 
    Clear pip's cache: pip cache purge, then retry the installation.
  2. 90% success 
    Bypass cache for a single install: pip install --no-cache-dir <package>.

Dead Ends

Common approaches that don't work:

  1. 80% fail

    Reinstalling pip does not clear the corrupted cache; the bad file remains and will be reused.

  2. 75% fail

    Force reinstall still reads from cache first; corrupted cache causes the same error.
