【问题描述】：

我无法摆脱错误。 有人提示为什么会这样？

我在版本 3 中使用带有路由器的 vuejs。

Uncaught TypeError: Object(...) is not a function

npm run serve

警告编译时有 2 个警告 ./src/router.js 中的警告“未找到导出‘createRouter’ ./src/router.js 中的“vue-router”警告“导出‘createWebHistory’ 在“vue-router”中找不到

router.js:

import  createWebHistory, createRouter  from "vue-router";
import UserSettings from "@/views/UserSettings.vue";
import UserEmailsSubscriptions from "@/views/UserEmailsSubscriptions.vue";
import UserProfile from "@/views/UserProfile.vue";
import UserProfilePreview from "@/views/UserProfilePreview.vue";
import Home from "@/views/Home.vue";
import About from "@/views/About.vue";
import Notfound from "@/views/Notfound.vue";

const routes = [
   path: "/:catchAll(.*)", name: "Notfound", component: Notfound ,
  
    path: "/",
    name: "Home",
    component: Home,
  ,
  
    path: "/about",
    name: "About",
    component: About,
  ,
  
    path: "/settings",
    // You could also have named views at tho top
    component: UserSettings,
    children: [
      
        path: "emails",
        component: UserEmailsSubscriptions,
      ,
      
        path: "profile",
        components: 
          default: UserProfile,
          helper: UserProfilePreview,
        ,
      ,
    ],
  ,
];

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

export default router;

App.vue

<template>
  <h1>Nested Named Views</h1>
  <router-view />
</template>

<script lang="ts">
export default 
  name: 'App'
;
</script>

main.js

"use strict";
exports.__esModule = true;

import  createApp  from 'vue'
import App from './App.vue'
import router from './router'

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

【参考方案1】：

您需要将 Vue Router 4 与 Vue 3 一起使用

npm install vue-router@4
