项目脚手架：vue-cli 3.x，用了 vue + vue-router + iview

iview为按需引入，用了：Row, Col, Button, Carousel, CarouselItem, Icon

问题描述

问题：在高版本浏览器访问正常，在安卓4.4.4 webview(内核为Chrome 33)中访问，页面空白，调试报错为：

尝试解决

看报错可能是ES6+语法问题，于是尝试通过添加polyfill，按vue-cli 3.x文档polyfill相关指南，使用了其第3种方式：

babel.config.js:

presets: [

['@vue/app', {

useBuiltIns: 'entry'

}]

]

main.js:

import '@babel/polyfill'

.browserslistrc:

chrome >= 33

android >= 4.4

测试问题没有解决
