根因分析

先前部分安装或损坏的包目录缺少必需的 METADATA 文件，导致 pip 在元数据验证期间失败。

English

A previously partially installed or corrupted package directory lacks the required METADATA file, causing pip to fail during metadata validation.

generic

解决方案

  1. 95% 成功率 Remove the corrupted package directory manually 
    Find the site-packages directory (e.g., `python -m site --user-site`), then delete the package folder (e.g., `rm -rf <package_name>-*`). Then reinstall.
  2. 85% 成功率 Use pip's `--no-cache-dir` and reinstall 
    `pip install --no-cache-dir --force-reinstall <package_name>`

无效尝试

常见但无效的做法:

  1. Reinstalling the package with `--force-reinstall` 50% 失败

    If the existing broken directory is not cleaned, pip may still encounter the same missing file.

  2. Manually creating an empty METADATA file 90% 失败

    The METADATA file must contain valid package metadata; an empty file will cause parsing errors.
