Question

我在r-studio version 1.1.463上运行macos Yosemite Version 10.10.5。我的笔记本电脑来自2015年初。每当我尝试在R-Studio中安装任何软件包时，都会出现以下错误消息：

对不起，我是一个完整的n00b，但是我不确定这是否意味着确实下载了软件包。如果安装了，我在哪里可以找到它们，以及如何将它们安装在R-Studio中？我没有C编译器，并且不确定我需要一个。

非常感谢。

请注意错误：“在以下位置未找到开发人员工具 '/Applications/Xcode.app'，请求安装。”
请注意，这也是从R Studio的依赖项页面中可以看到：“核心软件 R包开发所需的开发实用程序可以是通过安装XCode命令行工具获得。你可以做这是两种方式之一。” source

您需要安装命令行开发人员工具。启动您的终端并执行：

xcode-select --install

然后重试安装。
