backend.js:1 [vue-devtools] Ready. Detected Vue v2.1.10

this is my store file and that's how I am importing it

store/store.js

import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

export default Vuex.Store({
  state: {
     counter: 0
  }
})

in my main.js

import store from './store/store'

new Vue({
  el: '#app',
  store,
  ...
}

please help whats wrong, I have used vue cli with webpack template vue init webpack myapp to generate it.

Replace export default Vuex.Store with export default new Vuex.Store.
Vuex.Store is not a normal function but a constructor.
