I'm getting the error at Vue.component. I've tried searching the web and couldn't find any working fixes on SO or google.

import Vue from 'vue'
import VueRouter from 'vue-router'
import Index from './Index.vue'
import Login from './Login.vue'

Vue.component(`index`, Index);
Vue.use(VueRouter)

const router = new VueRouter({
  mode: 'history',
  routes: [
    { path: '/', component: Login },
  ]
})

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