Unable to run the Router.

I am totally new on Laravel + VueJs. I am using laravel 8 and VueJS 2.6.12 with Vue-Router 3.5.2.

I am getting following error when I run command below:

*npm run dev*

I have no idea where am I making mistake?

Dashboard.vue

<template>
    <div class="container">
        <div class="row justify-content-center">
            <div class="col-md-8">
                <div class="card">
                    <div class="card-header">Dashboard</div>

                    <div class="card-body">
                        I'm an dashboard component.
                    </div>
                </div>
            </div>
        </div>
    </div>
</template>

<script>
    export default {
        mounted() {
            console.log('Component mounted.')
        }
    }
</script>

app.js

require('./bootstrap');

import Vue from 'vue'
import VueRouter from 'vue-router'
import Dashboard from './components/Dashboard.vue'

Vue.use(VueRouter)

let routes = [
  { path: '/dashboard', component: Dashboard }
]

const router = new VueRouter({
  routes: routes
})

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

Here is my package.json file. I have VueJS 2.6.12 with Vue-Router 3.5.2.
