Locate in the following code and you can see that it is the wrong component of the component

export default new Router({
  routes: [
    {
      path:'/',
      redirect:'/home'
    },
    {
      path:'/home',
      component:'Home'
    },
    {
      path:'/cart',
      component:'Cart'
    },
    {
      path:'/profile',
      component:'Profile'
    }
  ]
})

After removing the quotation marks (component: profile), the interface can be displayed normally.
