uncaught syntax error and identifier with Vuex

I am learning Vuex but having challenge to run mapState and i assume mapGetters and mapMutations will also impose the same challenge.

I am running the code in xampp localhost in non-node environment and i keep receiving errors like 

Uncaught SyntaxError: Unexpected token {

This is my code below:

index.html

<script src="./vue.js"></script>
<!--<script src="./vuex.min.js"></script>-->

<div id="app">
  <counter></counter>
  <p>
    <button @click="increment">+</button>
    <button @click="decrement">-</button>
  </p>
</div>
<script src="./example.js"></script>

example.js

import { mapState } from './vuex.min';

const store = new Vuex.Store({
  state: {
    count: 0
  },
  mutations: {
    increment: state => state.count++,
    decrement: state => state.count--
  }
})

const Counter = {
  template: `<div>{{ count }}</div>`,
  /*computed: {
    count () {
      return this.$store.state.count
    }
  }*/
  computed:mapState({})

  /*
     I have inserted mapState this way

     though the example given is

     import { mapState } from 'vuex';

     export default {
        computed: mapState({
           //some codes here
        })
     }

  */

}

const app = new Vue({
  el: '#app',
  store,
  components: { Counter },
  methods: {
    increment () {
      store.commit('increment')
    },
    decrement () {
        store.commit('decrement')
    }
  }
})

I am sure there must be mistake somewhere or yet to declare something to make it work that's the reason am seeking for help; i've tried many ways even install Vue devtool extension into chrome but couldn't start the devtool to enable me run the code in vue devtool.

You cannot ES6 export from compressed (production) builds. You need to export with Vuex.mapState()

Here is working example.
