当我在Vue 3中使用async setup ()时，我的组件消失了。为什么我在Vue3中使用async setup（）时会出现空白...它工作正常，但当我使用router-view时却出现空白页。

<template>
    <div v-if="error">{{error}}</div>
    <Suspense>
        <template #default>
            <router-view></router-view>
        </template>
        <template #fallback>
            <Loading />
        </template>
    </Suspense>
</template>

<script>
import Loading from "./components/Loading"
import { ref, onErrorCaptured } from "vue"

export default {
    name: 'App',
    components: { Loading },
    setup() {
        const error = ref(null)
        onErrorCaptured(e => {
            error.value = e
        })
    }
}
</script>

• 主文件名.js：*

import { createApp } from 'vue'
import router from "./router"
import App from './App.vue'

createApp(App).use(router).mount('#app')

当我用我的一个组件替换router-view时，它就出现了。

• 路由器：*

import { createWebHistory, createRouter } from "vue-router";
import Portfolio from "@/views/Portfolio.vue";
import Blog from "@/views/Blog/Blog.vue";
import Detail from "@/views/Blog/Detail.vue";
import NotFound from "@/views/NotFound.vue";

const routes = [
    {
        path: "/",
        name: "Home",
        component: Portfolio,
    },
    {
        path: "/blog",
        name: "blog",
        component: Blog,
    },
    {
        path: "/blog/:slug",
        name: "detail",
        component: Detail,
    },
    {
        path: "/:catchAll(.*)",
        component: NotFound,
    },
];

const router = createRouter({
    history: createWebHistory(),
    routes,
});

export default router;
