在nodejs目录下输入命令npm install -g @vue/cli
报错如下:
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! [email protected] postinstall: `node scripts/postinstall`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the [email protected] postinstall script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

解决办法:
npm install @vue/cli -g --ignore-scriptsnpm install protobufjs -g --ignore-scripts再查看vue --version成功了

查看vue版本的时候报错：
internal/modules/cjs/loader.js:783
throw err;

}
解决方法：
是因为vue脚手架没有全局安装。
npm install -g @vue/cli

解决方法：
重点是这里的：npm ERR! Error: EPERM: operation not permitted
其实就是权限问题，使用管理员权限应该OK。
选择"使用管理员权限运行CMD"；然后继续输入命令即可。
