1、router.js裡面

{
      path: '/about',
      name: 'about',
      // route level code-splitting
      // this generates a separate chunk (about.[hash].js) for this route
      // which is lazy-loaded when the route is visited.
      component: () => import(/* webpackChunkName: "about" */ './views/About.vue
 
')
    }

webpackChunkName

註釋的webpackChunkName就類似於起了一個別名
