问题描述

在IE下显示空白页面，具体错误信息如下：

图片描述

问题出现的环境背景及自己尝试过哪些方法

npm install --save babel-polyfill

在入口处增加

import 'babel-polyfill'

下面的代码我不知道加在什么位置

module.exports = {

entry: ["babel-polyfill", "./app/js"]

};

相关代码

我的项目目录：

core

app.js(入口文件)

APP.vue

lavas.config.js

ecosystem.config.js

app.js 代码

/**

* @file entry

* @author

*/

import 'babel-polyfill'

import Vue from 'vue'

import Meta from 'vue-meta'

import i18n from '@/front-core/lib/i18n'

import chart from '@/front-core/lib/chart'

import CountTo from 'vue-count-to'

import Color from 'color'

import { createRouter } from '@/.lavas/router'

import { createStore } from '@/.lavas/store'

import AppComponent from './App.vue'

import fly from '@/fetch'

// 图表样式

import chartTheme from '@/assets/stylus/chart.theme'

import './element-ui'

Vue.use(Meta)

Vue.prototype['$http'] = fly

// 注册全局color

Vue.Color = Vue.prototype['$Color'] = Color

Vue.config.productionTip = false

export const version = (Vue.prototype.version = 'mvp')

export function createApp() {

let router = createRouter()

let store = createStore()

let App = Vue.extend({

router,

store,

...AppComponent

})

return { App, router, store }

}

if (module['hot']) {

module['hot'].accept()

}

lavas.config.js 代码

'use strict'

const path = require('path')

const BUILD_PATH = path.resolve(__dirname, 'dist')

const isDev = process.env.NODE_ENV === 'development'

module.exports = {

build: {

ssr: false,

path: BUILD_PATH,

publicPath: '/',

ssrCopy: isDev

? []

: [

{

src: 'server.prod.js'

},

{

src: 'package.json'

}

],

watch: ['/front-core', '/store'],

extend(config, { type }) {

if (type === 'base') {

config.module.rules.push({

test: /\.json$/,

use: 'json-loader'

})

}

}

},

middleware: {

all: ['viewer']

},

//重写路由配置项

router: {

mode: 'history',

base: '/',

pageTransition: {

type: 'fade',

transitionClass: 'fade'

},

// routes 包括一个类型自动转的部分

routes: [

pattern: new RegExp(`\\/_id`),

lazyLoading: true,

}

]

},

serviceWorker: {

swSrc: path.join(__dirname, 'core/service-worker.js'),

swDest: path.join(BUILD_PATH, 'service-worker.js'),

// swPath: '/custom_path/', // specify custom serveice worker file's path, default is publicPath

globDirectory: BUILD_PATH,

globPatterns: ['**/*.{html,js,css,eot,svg,ttf,woff}'],

globIgnores: ['sw-register.js', '**/*.map'],

appshellUrl: '/appshell',

}

}

你期待的结果是什么？实际看到的错误信息又是什么？

兼容IE即可，目前除了IE其他浏览器均兼容
