## 根因

pip 正在安装到由 root 拥有的系统 site-packages 目录，但没有足够的权限。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |

## 解决方案

1. **** (99% 成功率)
   ```
   python3 -m venv .venv
source .venv/bin/activate
pip install mypkg
   ```
2. **** (90% 成功率)
   ```
   python3 -m pip install --user mypkg
   ```

## 无效尝试

- **** — Installing as root pollutes the system Python and can break OS tooling; also may still fail on immutable dirs. (40% 失败率)
- **** — Weakens system security and can break other tools relying on permissions. (70% 失败率)
- **** — --user is ignored when running as root, so it still targets system site-packages. (85% 失败率)
