Root Cause

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

generic

中文

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。

Workarounds

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

Dead Ends

Common approaches that don't work:

  1. 60% fail

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

  2. 80% fail

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