根因分析

sys.path 上存在多个 site-packages 位置；pip 看到的是一个已安装副本，而另一个副本将其遮蔽。

English

Multiple site-packages locations on sys.path; pip sees one installed copy while another shadows it.

解决方案

  1. 95% 成功率 
    python -m venv .venv
source .venv/bin/activate
pip install foo
  2. 75% 成功率 
    python -c "import sys; print('\n'.join(sys.path))"
python -m pip install --target=/custom/path foo

无效尝试

常见但无效的做法:

  1. 60% 失败

    Reinstalls into one location while the shadowing copy remains, so the wrong version still imports.

  2. 80% 失败

    Removing system packages can break OS tooling and is often not permitted.
