Cant not import Vue + VueRouter correctly

I am trying to import Vue and VueRouter correctly, but I always get the following warnings.

app.js

import Vue from 'vue';
import VueRouter from 'vue-router';
import routes from './routes';

Vue.use(VueRouter);

let app = new Vue({
    el: '#app',

    router: new VueRouter(routes)
});

Warnings in console
