根因分析

pip 缓存目录由其他用户（通常是之前 sudo pip 运行的 root）创建，或权限受限，因此 pip 无法写入并禁用缓存。

English

The pip cache directory was created by another user (often root from a prior sudo pip run) or has restrictive permissions, so pip cannot write to it and disables caching.

解决方案

  1. 92% 成功率 
    Reclaim ownership: sudo chown -R $USER:$USER ~/.cache/pip
  2. 85% 成功率 
    Point the cache elsewhere: pip config set global.cache-dir ~/.cache/pip-user  # or export PIP_CACHE_DIR=~/.cache/pip-user

无效尝试

常见但无效的做法:

  1. 50% 失败

    Silences the warning by skipping cache entirely but leaves the root-owned directory in place; every future install re-warns.

  2. 90% 失败

    Makes root the owner again, guaranteeing the non-root user still cannot write; the warning persists.
