Vue-router page jump no answer

the page cannot jump during a vue-router jump. My code is as follows:

Index.js
import Vue from "vue"
import Router from" vue-router"

in

routrt

Vue.use (Router)
const Loading = resolve = > require ([".. / Views/Loading"], resolve)
const Layout = resolve = > require ([".. / Views/Layout"], resolve)
const Demo = resolve = > require ([".. / Views/Demo01"], resolve)
const Infromation = resolve = > require ([".. / Views/Infromation"], resolve)
const Like = resolve = > require ([".. / Views/Like"], resolve)
const Skill = resolve = > require ([".. / Views/Skill"] Views/Skill"

const router = new Router ({
routes: [

{
  path: "/Loading",
  name: "Loading",
  meta:{
    requireAuth: false
  },
  component: Loading
},
{
  path: "/",
  name:"Layout",
  meta: {
      requireAuth: true
  },
  component: Layout,
  redirect: "/Layout", // 
  children:[{
    path:"/Infromation",
    mata:{
      requireAuth: true
    },
    component: Infromation
  },{
    path:"/Like",
    meta:{
      requireAuth: true
    },
    component:true
  },{
    path:"/Skill",
    meta:{
      requireAuth:true
    },
    component:Skill
  }]
}

]
})
