Answer 1

错误信息已经提示了/Users/helloimyhe/Documents/happylearn-admin-html/trunk/happylearn-admin-html/node\_modules/.bin/vue-cli-service: Permission denied没有权限;
需执行命令:

chmod 777 /Users/helloimyhe/Documents/happylearn-admin-html/trunk/happylearn-admin-html/node\_modules/.bin/vue-cli-service

然后重新执行

npm run serve

Answer 2

我也遇到了这么问题，在网上看到了别的大神把这个问题解决了，解决方案是在根目录下新建一个vue.config.js文件，里边配上
`module.exports = {

devServer: {
    clientLogLevel: 'info'
}

};`
