vue cli3 兼容ie8以上浏览器，前端兼容；解决ie浏览器下白屏问题

1下载 babel-polyfill 模块

npm install babel-polyfill -s

2入口文件（main.js）第一行引入

import "babel-polyfill";
import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import Button from 'ant-design-vue/lib/button';
import Antd from 'ant-design-vue'
import 'ant-design-vue/dist/antd.css';
import zh_CN from 'ant-design-vue/lib/locale-provider/zh_CN';
import moment from 'moment';
import 'moment/locale/zh-cn';
import './assets/iconfont/iconfont';
import axios from 'axios'Vue.component(Button.name, Button);Vue.config.productionTip = falseVue.use(Antd)
// Vue.use(axios)moment.locale('zh-cn');
new Vue({zh_CN,router,store,render: h => h(App)
}).$mount('#app')

3.配置 polyfill，在根目录下新增babel.config.js文件：

module.exports = {presets: [['@vue/app', {useBuiltIns: 'entry'}]]
}

原来有此文件就直接修改

module.exports = {presets: [// '@vue/cli-plugin-babel/preset', //文件原始内容['@vue/cli-plugin-babel/preset', {useBuiltIns: 'entry'             //添加的内容}]]
}
