引起的主要原因是，ie无法解析es6语法。需要引入babel-polyfill
第一步：npm install babel-polyfill --save-dev
第二步：在webpack.base.config.js中
require('babel-polyfill') module.exports = { entry: { app: ['babel-polyfill', './src/main.js'] } }有些插件还出错需要另外设置（例如iview）
{ test: /\.js$/, loader: 'babel-loader', include: [resolve('src'), resolve('test'), resolve('node_modules/iview')] },参考：解决webpack项目在ie下报错
