vue-cli 项目使用vue-router的问题

Question

问题是：<router-view></router-view>中不渲染匹配到的component！

先贴一下package.json:

  },

    "node": ">= 4.0.0",
    "npm": ">= 3.0.0"
  }
}

main.js代码如下：

import Vue from 'vue'
import VueRouter from 'vue-router'
import App from './App'
import Index from './components/Index.vue'
import Login from './components/Login.vue'
Vue.use(VueRouter)

const router = new VueRouter({
  routers: [
    {
      path: 'login',
      component: Login
    },
    {
      path: '/',
      component: Index
    }
  ]
})

const app = new Vue({
  router,
  el: '#app',
  template: '<App/>',
  components: { App }
})

App.vue代码如下：

<template>
  <div id="app">
    <img src="./assets/logo.png">
    <p>
      <router-link to="/login">Login</router-link>
      <router-link to="/">Index</router-link>
    </p>
    <router-view></router-view>
  </div>
</template>

<script type="text/ecmascript-6">

export default {
  data(){
      return {

      }
  },
  methods: {
  },
  components: {
  }
}
</script>

<style scoped>
#app {
  font-family: 'Avenir', Helvetica, Arial, sans-serif;
  -webkit-font-smoothing: antialiased;
  -moz-osx-font-smoothing: grayscale;
  text-align: center;
  color: #2c3e50;
  margin-top: 60px;
}
</style>

Index.vue代码如下：

<template>
  <div class="index">
    <h1>Hello</h1>
  </div>
</template>
<style>
</style>
<script>
    export default{
        data(){
            return {}
        },
        components: {

        }
    }
</script>

yarn run dev 以后无法显示Index.vue template中的内容:

Answer 1

const router=new VueRouter({
    routes:[{
        path:'/',component:Index
    }]
})

是routes不是routers

Answer 2

关键步骤罗列一下：
const routes = [
{ path: '/foo', component: Foo },
{ path: '/bar', component: Bar }
]

const router = new VueRouter({ routes })

const app = new Vue({ router}). $mount('#app')
