## 根因

该解释器未安装 pip（常见于精简的 Debian/Ubuntu 镜像中 python3-pip 是单独包，或新编译/嵌入式 Python 未包含 ensurepip）。

## 无效尝试

- **** — pip isn't installed, so the command itself fails. (95% 失败率)
- **** — pip isn't present anywhere on disk. (90% 失败率)
- **** — Only works if that interpreter has pip; the target one still doesn't. (70% 失败率)
