typescript - Vue.js 3和typescript:类型'ComponentPublicInstance上不存在 '$store'属性

Question

找不到任何东西可以解决这个看似明显的问题。
刚刚从Type 2的Vue 2升级到Vue 3和Vuex。
尽管遵循Vue 3的说明，但似乎无法访问this。$ store。

ERROR in src/components/FlashMessages.vue:28:25TS2339: Property '$store' does not exist on type 'ComponentPublicInstance<{}, {}, {}, { getAllFlashMessages(): Word; }, {}, EmitsOptions, {}, {}, false, ComponentOptionsBase<{}, {}, {}, { getAllFlashMessages(): Word; }, {}, ComponentOptionsMixin, ComponentOptionsMixin, EmitsOptions, string, {}>>'.

    26 |     computed: {
    27 |         getAllFlashMessages (): FlashType {
  > 28 |             return this.$store.getters.getFlashMessages;
       |                         ^^^^^^
    29 |         },
    30 |     },
    31 | 

主要

import { createApp } from 'vue'
import App from './App.vue'
import './registerServiceWorker'
import router from './router'
import store from './store'
import './assets/styles/index.css'

const app = createApp(App)

app.use(store)
app.use(router)
app.mount('#app')

商店

import { createStore } from 'vuex'
import FlashType from '@/init'

export default createStore({
    state: {
        flashMessages: [] as FlashType[],
    },

    getters: {
        getFlashMessages (state) {
            return state.flashMessages
        }
    },

FlashMessages.vue

<script lang="ts">
import { defineComponent } from "vue";
import FlashType from "@/init";

export default defineComponent({
    name: "FlashMessages",

    data () {
        return {};
    },

    computed: {
        getAllFlashMessages (): FlashType {
            return this.$store.getters.getFlashMessages;
        },
    },

初始化

export type FlashType = {
    kind: 'success' | 'error';
    message: string;
    time: number;
}

任何智慧表示赞赏:)

这是我第一次正确使用eslint，所以我不确定是否设置正确。.我最终在/ client和/ server目录中使用了另一个tsconfig。
客户端/ tsconfig.json

    "target": "esnext",
    "module": "esnext",

Answer 1

在shims-vue.d.ts文件旁边，创建另一个名为shims-vuex.d.ts的文件，其内容如下:

import { Store } from '@/store';// path to store file

declare module '@vue/runtime-core' {
  interface ComponentCustomProperties {
    $store: Store;
  }
}
