vue 懒加载组件chunk相对路径混乱问题及解决

//router.js
import VueRouter from 'vue-router'
const A = () => import('./pages/a.vue');
const B = () => import('./pages/b.vue');
const AA = () => import('./pages/a.a.vue');
const AB = () => import('./pages/a.b.vue');
const routes = [
    {
    path: '/a', component: A,children:[{
        path:'a', component:AA
    },{
        path:'b', component:AB
    }]
}, 
{
    path: '/b/:id', component: B, props: true
}]
const router = new VueRouter({
    mode: 'history',
    routes
})
export default router;

//webpack.config.js
config.output.publicPath = '/';

const routes = [
    {
        path: '/',
        component: App
    },
    {
        path: '/category',
        component: resolve => {require(['./components/Category.vue'], resolve)}
    }
]

Elixir.webpack.mergeConfig({
    module: {
