[Vue warn]: Unknown custom element: <router-view> - did you register the component correctly?

Question

I use Vue 2 in CLI mode with webpack-simple. I have following files:

main.js:

import Vue from 'vue';
import App from './App.vue';
import VueRouter from 'vue-router';
import Routes from './routes';
    
Vue.use('VueRouter');
    
const router = new VueRouter({
  routes: Routes,
});
    
new Vue({
  el: '#app',
  render: h => h(App),
  router: router,
});

App.vue:

<template>
  <div>
    <router-view></router-view>
  </div>
</template>
    
<script>
import Loader from './Loader.vue';
    
export default {
  name: 'app',
}
</script>
    
<style lang="scss">
</style>

routes.js:

import Game from './components/Game.vue';
import Login from './components/Login.vue';
    
export default [
  { path: '/', component: Game, name: "Game" },
  { path: '/login', component: Login, name: "Login" },
]

Game.vue and Login.vue looks the same:

<template>
  <div>
    Game
  </div>
</template>
    
<script>
export default {
  name: 'game',
}
</script>
    
<style lang="scss">
div {
  border: 1px solid red;
  width: 100px;
  height: 100px;
}
</style>

unfortunately starting a file gives me an error:

[Vue warn]: Unknown custom element: - did you register the component correctly? For recursive components, make sure to provide the "name" option.

Also router-view tag is not changed to proper html. I use vue router for the first time. It' been installed via npm in version 3.0.1

Any advice?

Answer 1

You need to do the following:

import Vue from 'vue';
import VueRouter from 'vue-router';
    
Vue.use(VueRouter);

Ref: https://router.vuejs.org/en/installation.html

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

Hope it will help you

Answer 2

Change:

Vue.use('VueRouter');

To:

Vue.use(VueRouter);
