angular - 安装 Angular CLI [问题：错误消息]

Question

MacBook-Pro-de-Arnold:first_app arnoldk.$ npm install -g @angular/cli
npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/@angular
npm ERR! errno -13

当我在终端上键入此语法时，我收到此错误消息：

npm install -g @angular/cli

这个安装会发生什么？我使用 MacBook Pro 2010 年中 macOs High Sierra 10.13.6
