包。要运行这些示例，你需要保持网络连接， 或者事先下载好这些依赖。要提前下载依赖，可以运行以下命令。（我们稍后会详细解释 cargo 是什么，以及这些命令分别的作用。） $ cargo new get-dependencies $ cd get-dependencies $ cargo add rand@0.8.5 trpl@0.2.0 这会将这些包的下载结果缓存起来，因此你之后就不需要再下载它们了。运行完该命令后，你 无需保留 mkdir ~/projects $ cd ~/projects $ mkdir hello_world $ cd hello_world 对于 Windows CMD，输入： > mkdir "%USERPROFILE%\projects" > cd /d "%USERPROFILE%\projects" > mkdir hello_world > cd hello_world 编写并运行 创建一个新项目，然后看看与上面的 “Hello, world!” 项目有什么不同。回到 projects 目录（或者你存放代码的目录）。接着，可在任何操作系统下运行以下命令： $ cargo new hello_cargo $ cd hello_cargo 第一行命令新建了名为 hello_cargo 的目录和项目。我们将项目命名为 hello_cargo，同时 Cargo 在一个同名目录中创建项目文件。 进入 hello_cargo
