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

然后提示输入电脑密码，运行即可
