这个意思是说在new Vue必须赋值给某个值的，强制不让eslink抱着个错的话，只需要在new Vue实例化之前添加/* eslint-disable no-new */就可以了
// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import App from './App'
import router from './router'
Vue.config.productionTip = false
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
})
