Vue-router error: TypeError: Cannot read property

Question

I'm trying to write my first Vuejs app. I'm using vue-cli and simple-webpack boilerplate.

When I add vue-router links to my app component I get this error in console

Error in render function: "TypeError: Cannot read property 'matched' of undefined"

Here is my code:

App.vue

<template>
  <div>
    <h2>Links</h2>
    <ul>
      <router-link to='/'>Home</router-link>
      <router-link to='/query'>Query</router-link>

      <router-view></router-view>
    </ul>
  </div>
</template>

<script>
    export default {}
</script>

main.js

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)
import routes from './routes.js'
import App from './App.vue'

const app = new Vue({
  el: '#app',
  routes,
  render: h => h(App)
})

routes.js

import VueRouter from 'vue-router';
let routes=[
  {
    path: '/',
    component: require('./Components/Home.vue')
  },
  {
    path: '/query',
    component: require('./Components/Query.vue')
  }
];

export default new VueRouter({routes});

Answer 1

On my Vue file I had the following code:

Then, I modified my app.js file, and place the following code:

import router from './Router/router.js'

const app = new Vue({
    el: '#app',
    router
});

The name when you add it to Vue must be router.

import router from './routes.js'

const app = new Vue({
  el: '#app',
  router,
  render: h => h(App)
})

If, for whatever reason, you want to call the variable routes you could assign it this way.

import routes from './routes.js'

const app = new Vue({
  el: '#app',
  router: routes,
  render: h => h(App)
})
