在Mac OS 下 npm install 报权限不足的错误

在Mac OS 下 npm install 报权限不足的错误

错误如下：

npm ERR! code EACCES
npm ERR! syscall mkdir
npm ERR! path /usr/local/lib/node_modules/@vue
npm ERR! errno -13
npm ERR! Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/@vue'
npm ERR!  [Error: EACCES: permission denied, mkdir '/usr/local/lib/node_modules/@vue'] {
npm ERR!   errno: -13,
npm ERR!   code: 'EACCES',
npm ERR!   syscall: 'mkdir',
npm ERR!   path: '/usr/local/lib/node_modules/@vue'
npm ERR! }
npm ERR! 
npm ERR! The operation was rejected by your operating system.

解决办法：

sudo npm install -g @vue/cli-service-global --allow-root 

然后提示输入密码，运行即可。特做笔记。
