Root Cause

pip lacks write permissions to the target site-packages directory, typically because it is owned by root or another user.

generic

中文

pip 缺少对目标 site-packages 目录的写入权限，通常是因为该目录属于 root 或其他用户。

Workarounds

  1. 90% success 
    pip install --user package
  2. 98% success 
    python3 -m venv myenv && source myenv/bin/activate && pip install package
  3. 70% success 
    sudo chown -R $USER /usr/local/lib/python3.9/site-packages

Dead Ends

Common approaches that don't work:

  1. 50% fail

    This can work but may cause permission issues later and is not recommended for user environments.

  2. 95% fail

    Reinstalling Python does not change directory ownership.

  3. 40% fail

    This may work but can lead to conflicts with system packages.
