## 根因

pip 安装失败，因为 pip 缓存或 site-packages 所在磁盘分区空间已满。常见于 /tmp 或根文件系统已满的情况。

## 版本兼容性

## 解决方案

1. **** (95% 成功率)
   ```
   pip cache purge && sudo apt-get clean && rm -rf /tmp/*
   ```
2. **** (85% 成功率)
   ```
   pip install --target=/mnt/bigdisk/python-packages package_name
   ```
3. **** (80% 成功率)
   ```
   export TMPDIR=/mnt/bigdisk/tmp && pip install package_name
   ```

## 无效尝试

- **** — Disabling cache does not free existing filesystem space and may still require temporary space for wheel building. (70% 失败率)
- **** — Timeout is unrelated to disk space; the error persists. (90% 失败率)
- **** — Elevated privileges do not create disk space and may write to a different partition but still fail. (80% 失败率)
