Vue.js &引用；出口'；商店'；在'；中找不到/商店'；

大家好，我正在尝试将我的店铺导入Vuex Route Gard

路由器/auth-guard.js

import {store} from '../store'
export default (to, from, next) => {
if (store.getters.user) {
  next()
} else {
next('/login')
}
}

store/index.js

import {store} from '../store'
export default (to, from, next) => {
if (store.getters.user) {
  next()
 } else {
 next('/login')
 }
}

我得到的错误 在“../store”中找不到导出“store”

我的vue设置

"dependencies": {
"firebase": "^4.3.0",
"vue": "^2.3.3",
"vue-router": "^2.6.0",
"vuex": "^2.3.1"

我能够通过这个方法解决这个问题

main.js

import {store} from './store'
new Vue({
  el: '#app',
  router,
  store,
  template: '<App/>',
  components: {
    App
  },

import {store} from '../store'
export default (to, from, next) => {
if (store.getters.user) {
  next()
 } else {
 next('/login')
}
}

Vue.use(Vuex)
export const store = new Vuex.Store({
modules: {
products,
bids,
user
}
})

store/index.js

import {store} from './store'
new Vue({
  el: '#app',
  router,
  store,
  template: '<App/>',
  components: {
    App
  },

import {store} from '../store'
export default (to, from, next) => {
if (store.getters.user) {
  next()
 } else {
 next('/login')
}
}

Vue.use(Vuex)
export const store = new Vuex.Store({
modules: {
products,
bids,
user
}
})
