vue-cli3.x 在使用路由按需加载以及嵌套路由时，进入子路由时报错

[H-Sven]

Version

3.2.1

When vue-cli3.x uses routing loading on demand and nested routing, it makes errors when it enters subrouting

Steps to reproduce

const router = new Router({
  routes: [
    {path: '*',name: '',redirect: '/index'},
    // 账户资料模块
    {
      path: '/',
      name: '首页',
      component:() =>import(/* webpackChunkName: "0" */ "./views/Home.vue"),
      children: [
        {path: 'index',name: '页面首页',component: () =>import(/* webpackChunkName: "1" */ "./views/Index.vue")},
        {path: 'order',name: '订单记录',component: () =>import(/* webpackChunkName: "2" */ "./views/Order.vue")},
        {
          path: 'assets',
          name: '资产',
          component: () =>import(/* webpackChunkName: "3" */ "./views/assets/Assets.vue"),
          children:[
            {path: 'index',name: '资产首页',component: () =>import(/* webpackChunkName: "4" */ "./views/assets/Index.vue")},
            {path: 'withdrawal',name: '提现',component: () =>import(/* webpackChunkName: "5" */ "./views/assets/Withdrawal.vue")},
            {path: 'record',name: '提现记录',component: () =>import(/* webpackChunkName: "6" */ "./views/assets/Record.vue")},
            {path: 'details',name: '账单明细',component: () =>import(/* webpackChunkName: "7" */ "./views/assets/Details.vue")},
            {path: 'recordDetails',name: '提现详情',component: () =>import(/* webpackChunkName: "8" */ "./views/assets/RecordDetails.vue")},
          ]
        },
        {
          path: 'account',
          name: '账户中心',
          component: () =>import(/* webpackChunkName: "9" */ "./views/account/Account.vue"),
          children:[
            {path: 'index',name: '账户中心首页',component: () =>import(/* webpackChunkName: "10" */ "./views/account/Index.vue")},
          ]
        },
      ]
    },
  ]
});

0,1,2,3,4.js all entered the routing normally. Then when I entered the same sub-routing 5 as 4, I loaded 5.js and a vendors105.js and 10~5.js at the same time. But the corresponding routing of 5 also entered normally. Then I visited the same 6.js corresponding routing as 5 and got the error mentioned above.

Why do you load JS like vendors105.js and 105.js?

What is expected?

正常进入子路由

What is actually happening?

无法进入子路由

1. 我们需要可运行的复现代码，靠截图无法帮忙排查问题
2. 根据 StackOverflow 上的回答，这个问题可能是因为你在 webpack 4 项目中引入了 webpack 3 打包后的代码 https://stackoverflow.com/questions/52447286/migrating-to-webpack-4-from-webpack-3
