我正在学习Vuejs，在我的项目中，我有一些警告和没有显示，因为我试图使用商店(VUEX)
所以我有:
├── index.html └── src ├── views └── Feed.vue └──store └── index.ts ├── App.vue ├── main.ts
我的主。ts:
// 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 Bootstrap

library.add(faUserSecret);

// 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");我。/存储/index.ts
// Imports
import { createApp } from 'vue'
import { createStore } from 'vuex'
import axios from 'axios';
//Create Store :
export const store = createStore({
// Define state

}
},
// Define Actions

</style>看起来我不懂Vuex的一些东西，但我不知道是什么。你能告诉我怎么了吗?(我希望不是很多事情:))/有人能帮我吗?请。
感谢看起来您正在从./store/index.ts中获取错误，您试图导出将函数调用应用于该行上的存储实例的结果:
export default store();
存储实例实际上不是一个函数，并且您在main.ts中导入结果。尝试只导出存储实例:
export default store
可能你不需要后面的行:
const app = createApp({})
app.use(store)
你得到这个错误是因为你试图调用一个对象，而不是一个函数。
您的错误位于./store/index.ts文件中。你犯了两个错误。第一个是您试图调用createStore两次。第二种是你试图从你的商店创建另一个应用。
在这里我分享给你的修复。
// createStore() retuns an object that you the pass it in your main.ts.
const store:any = createStore({
// all your store definitions...
})
在同一个文件的末尾，您应该只导出createStore()返回的对象，这样您就可以在app.use()(位于main.ts中)注册它。
export default store
// remove the code bellow...
编辑:您还在setup选项中犯了一个错误。您应该导入已经创建的存储。
import { store } from 'path/to/your/store/index.ts'
setup () {
const myStore = store
// property data doesn't exist in your state.
const feedList = computed(() => myStore.state.feedList);
console.log("feedList > " + feedList.value);
return {
feedList
}
除了卢卡斯·大卫·费雷罗的精彩回答，我还忘了一件事....在我的Feed里。Vue:安装商店!!所以我的文件现在是:
<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>
</div>
</template>
<script lang="ts">
import Cartridge from '@/components/Cartridge.vue';
import SendPost from '@/components/SendPost.vue';
import { computed } from 'vue'
import { store } from '../store/index'
export default {
name: 'Feed',
components: {
Cartridge,
SendPost,
},
setup() {
const myStore: any = store
const feedList = computed(() => myStore.state.feedList);
console.log("feedList > " + feedList.value);
return {
feedList
};
},
mounted() {
const myStore: any = store
myStore.dispatch("getPosts");
}
}
