vue-router should route on click, not working

I am trying to create a navigation and when someone clicks. It should navigate to another Vue.component.

Note: This app is Electron+Vue based, but it should work as normal Vue Project, as i've tried same concept in other Electron+Vue Project too.

Right now it shows no Content because of error of Router. Am i missing anything?

Error Shows like this in Screenshot

new Vue({
    render: function (h) { return h(App) },

----App.vue------

<template>
  <div id="app">

   <HelloWorld msg="Welcome to Your Vue.js App"/>
       <main>
         <router-view></router-view>
       </main>
     </div>
  </template>

 <script>
    import HelloWorld from './components/HelloWorld.vue'

     export default {
      name: 'App',
      components: {
        HelloWorld
      }
    }
 </script>

A help would be Appreciated.

Instead of exporting the router, put in a const and specify it inside new Vue({

main.js

const router = new VueRouter({
  routes: [
    ...
  ],
  // Prevent white screen on reload (in production build)
  mode: process.env.IS_ELECTRON ? 'hash' : 'history'
})


new Vue({
  router,
  render: h => h(App),
  mounted () {
    // Prevent white screen when the app is launched (in production build)
    this.$router.push('/').catch(error => { })
  }
}).$mount('#app')
