Vue my component always does not show what is going on?

Why can"t note components be displayed? Several errors have been prompted [vuex] must call Vue.use (Vuex) before creating a store instance.

and store.js prompts "Vue" is defined but never used
main.js also hints " store" is defined but never used

note.vue

<template>
  <div>
    aaaa
    {{msg}}
  </div>
</template>

<script>
export default {
  name: "note",
  data () {
    return {
    }
  },
  computed: {
    msg () {
      return this.$store.state.msg
    }
  }
}
</script>

<style scoped>
</style>

main.js

import Vue from "vue"
import App from "./App"
import router from "./router"
import Mint from "mint-ui"
import "mint-ui/lib/style.css"
import Vuex from "vuex"
import store from "./store/store.js"

Vue.use(Vuex)
Vue.use(Mint)

Vue.config.productionTip = false

/* eslint-disable no-new */
new Vue({
  el: "-sharpapp",
  router,
  components: { App },
  template: "<App/>"
})

router/index.js

import Vue from "vue"
import Router from "vue-router"
import Note from "@/components/Note"

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: "/",
      name: "note",
      component: Note
    }
  ]
})

APP.vue

<template>
  <div id="app">
    <router-view/>
  </div>
</template>

<script>
export default {
  name: "App"
}
</script>

<style>
</style>

store.js

import Vue from "vue"
import Vuex from "vuex"

export default new Vuex.Store({
  state: {
    msg: "aaa"
  },
  mutations: {
  },
  components: {
  },
  modules: {
  },
  actions: {
  }

new Vue({

  router,
  store, // ---  
  components: { App },
  template: '<App/>'
})

Remove Vuex from

main.js and remove

from Vue.use (Vuex).

add Vue.use (Vuex) to store

store should also be used. Either remove it or remove everything that is not used by registered variables

.

you can know the meaning by reading English. It is suggested that the registration is not in use because you have used the syntax check of eslint. You can learn or turn off the corresponding configuration

.

you didn't transfer store into new Vue, and then remove Vue.use (Vuex)
