# 错误：要修改 pip，请运行以下命令：
/home/user/venv/bin/python -m pip install --upgrade pip

- **ID:** `python/pip-install-requires-pip-version`
- **领域:** python
- **类别:** install_error
- **验证级别:** ai_generated
- **修复率:** 80%

## 根因

当 pip 检测到正在运行的 pip 位于自我修改不安全的位置时，它拒绝通过 `pip install --upgrade pip` 自我升级；它会指示你改用 `python -m pip`。

## 版本兼容性

| 版本 | 状态 | 引入 | 弃用 |
|------|------|------|------|
| 3.x | active | — | — |

## 解决方案

1. **** (95% 成功率)
   ```
   Run pip as a module: python -m pip install --upgrade pip
   ```
2. **** (90% 成功率)
   ```
   Upgrade in a fresh venv: python -m venv .venv && . .venv/bin/activate && python -m pip install --upgrade pip
   ```

## 无效尝试

- **** — Force-reinstall still routes through the same self-modification guard and prints the identical refusal. (70% 失败率)
- **** — Privilege escalation doesn't lift the guard and may install a second pip into a different site-packages, causing version confusion. (75% 失败率)
