interacting with the system. Note: the GUI is enabled by default in 1.2 clusters.

     由于此文件**不经常更改**，Docker 将检测到它并在这一步中使用**缓存**，从而为下一步启用缓存。

4. 安装需求文件中的包依赖项。

     `--no-cache-dir` 选项告诉 `pip` 不要在本地保存下载的包，因为只有当 `pip` 再次运行以安装相同的包时才会这样，但在与容器一起工作时情况并非如此。

     /// note | 笔记

     `--no-cache-dir` 仅与 `pip` 相关，与 Docker 或容器无关。

     ///

     `--upgrade` 选项告诉 `pip` 升级软件包（如果已经安装）。

     因为上一步复制文件可以被 **Docker 缓存** 检测到，所以此步骤也将 **使用 Docker 缓存**（如果可用）。
