In vue routing, router-link can jump addresses, but router-view cannot render.

this is main.js

import Vue from "vue"
import VueRouter from"vue-router";
import App from "./App"
import Routes from "./router"

Vue.use(VueRouter)

let router = new VueRouter({
    Routes
})
new Vue({
    router,
    render:h=>h(App)
}).$mount("-sharpapp")

this is App.vue

<template>
  <div id="app">
    <v-header></v-header>
    <div class="tab">
      <div class="tab-item">
        <router-link to="/goods"></router-link>
      </div>
      <div class="tab-item">
        <router-link to="/comment"></router-link>
      </div>
      <div class="tab-item">
        <router-link to="/seller"></router-link>
      </div>
   
    </div>
      <router-view></router-view> 
    <!--  -->
    <!--  -->
</div>
</template>

this is router/index.js

import Vue from "vue"
import Router from "vue-router"
import goods from "@/components/goods/goods"
import comment from "@/components/comment/comment"
Vue.use(Router)

export default new Router({
  routes:[
    {
      path: "/comment",
      name: "comment",
      component:comment
    },
    {
      path: "/goods",
      name: "goods",
      component: goods
    }
  ]
})

this is the component

<template>
    <div>I am goods</div>
</template>
<script type="text/script"></script>
<style lang="stylus" rel="stylesheet/stylus"></style>

Why does the content of App.vue appear and the router-link click address of App.vue also jumps, but router-view cannot render the content in the component

landlord, there is something wrong with the writing in
main.js . Try the following one


router/index.js new Router;<br>main.js

let router = new VueRouter({
    Routes
})

the following is modified to look like this

new Vue({
    Routes,
    render:h=>h(App)
}).$mount("-sharpapp")

-supplement

export default new Router({
  routes:[
    {
      path: '/comment',
      name: 'comment',
      component:comment
    },
    {
      path: '/goods',
      name: 'goods',
      component: goods
    }
  ]
})

changed to

export default new Router({
  [
    {
      path: '/comment',
      name: 'comment',
      component:comment
    },
    {
      path: '/goods',
      name: 'goods',
      component: goods
    }
  ]
})
