VueJs 3 – Vuex: Nicht erfasster TypeError: Speicher ist keine Funktion

Question

Ich lerne Vuejs und in meinem Projekt, seit ich versucht habe, Store (VUEX) zu verwenden, habe ich einige Warnungen erhalten und nichts wurde angezeigt

Also ich habe:

├── index.html
└── src
     ├── views
        └── Feed.vue      
     └──store
       └── index.ts
     ├── App.vue
     ├── main.ts

Mein main.ts ist:

// initialisation des éléments pours VUE
import { createApp } from "vue";
import App from "./App.vue";
import "./registerServiceWorker";
import router from "./router";
import store from "./store";
import axios from 'axios'
import VueAxios from 'vue-axios'


// initialisation des imports pour Font Awesome
import { library } from "@fortawesome/fontawesome-svg-core";
import { faUserSecret } from "@fortawesome/free-solid-svg-icons";
import {
  faSpinner,
  faPaperPlane,
  faHandPeace,
  faSignOutAlt,
  faShieldAlt,
  faUserPlus,
  faImage,
  faEdit,
  faUsersCog,
  faTools,
  faRss,
  faTimesCircle,
} from "@fortawesome/free-solid-svg-icons";
import { FontAwesomeIcon } from "@fortawesome/vue-fontawesome";

// initialisation des imports pour Bootstrap
import "bootstrap/dist/css/bootstrap.min.css";
import "bootstrap";
import "bootstrap/dist/js/bootstrap.js";

// intégration des icones font awesome à la librairy
library.add(faUserSecret);
library.add(faSpinner);
library.add(faPaperPlane);
library.add(faHandPeace);
library.add(faSignOutAlt);
library.add(faShieldAlt);
library.add(faUserPlus);
library.add(faImage);
library.add(faEdit);
library.add(faEdit);
library.add(faUsersCog);
library.add(faTools);
library.add(faRss);
library.add(faTimesCircle);


// Création de l'app
const app = createApp(App);
  app.use(store);
  app.use(router);
  app.use(VueAxios, axios);
  app.provide('axios', app.config.globalProperties.axios) ;
  app.component("font-awesome-icon", FontAwesomeIcon);
  app.mount("#app");

my./store/index.ts

// Imports 
import { createApp } from 'vue'
import { createStore } from 'vuex'
import axios from 'axios';


//Create Store :

export const store = createStore({

  // Define state
  state () {
    return{
      feedList: []
    }
  },

  // Define Actions
  actions: {
    getPosts( { commit } ) {
      axios.get('http://localhost:3001/api/feed')
          .then(feedList => {
            commit('setFeedList', feedList)
      })
    }
  },

  // Define mutations
  mutations: {
    setFeedList(state:any, feedList:any) {
      state.data = feedList
    }
  }, 

})

Mein ./views/Feed.vue:

<template>
  <div id="Feed">
    <div id="profil" class="col-12 col-md-3">
      <Cartridge />
    </div>
    <div id="feedcontent" class="col-12 col-md-9">
      <SendPost />
      <div id="testlist" v-for="thePost in feedList" :key="thePost">
        {{ thePost }}
    </div>
  </div>
</template>

<script lang="ts">
import Cartridge from '@/components/Cartridge.vue';
import SendPost from '@/components/SendPost.vue';
import { computed } from 'vue'
import { useStore } from 'vuex'

export default {
  name: 'Feed',
  components: {
    Cartridge,
    SendPost
  },

  setup () {
    const store = useStore();

    const feedList = computed(() => store.state.data.feedList);
    console.log("feedList > " + feedList.value);
    return {
      feedList
    }
  },
}
</script>

<style lang="scss">
@import "../scss/variables.scss";

#profil {
  position: fixed;
  margin: 0;
  height: 100%;
}

#feedcontent {
  position: fixed;
  height: 100%;
  right: 0;
  background-color: $groupo-colorLight1;
  overflow-y: scroll;

  ::-webkit-scrollbar {
    width: 8px;
    color: $groupo-color1;
  }

  ::-webkit-scrollbar-track {
    background: $groupo-colorLight2;
    width: 20px;
    -webkit-box-shadow: inset 0 0 6px rgba($groupo-color4, 0.3);
  }

  ::-webkit-scrollbar-thumb {
    background: $groupo-color4;
  }

  ::-webkit-scrollbar-thumb:hover {
    background: $groupo-color1;
  }
}
</style>

Sieht so aus, als ob ich etwas in Vuex nicht verstehe, aber ich weiß nicht was. Kannst du mir sagen, was los ist? (Ich hoffe, es ist nicht viel :)) / Kann mir jemand helfen? Bitte.

Danke

Answer 1

看起来您从 ./store/index.ts 中的行中收到错误，您试图将函数调用应用到此行上的商店实例的结果导出：

export 默认存储();

商店实例确实不是一个函数，您将结果导入 main.ts 中。尝试仅导出商店实例：

export默认商店

也许您不需要之后的行：

const app = createApp({})
app.use(store)

不仅仅是 @Lucas David Ferrero 的真正好的答案，我在我的 Feed.vue 中忘记了一件事......：安装了商店！ 所以我的文件现在是：
