Vue3“在‘vue-router’中找不到导出‘createWebHistory，createRouter’

我正在创建一个 Vue3 应用程序，添加路由器后，我的第一页正在加载，但它完全是空白的。

我收到以下信息

错误：未捕获类型错误：对象（...）不是函数

在控制台中：

./src/router/index.js 中出现警告“未找到导出‘createRouter’ 在“vue-路由器”中

./src/router/index.js 中的警告“未导出‘createWebHistory’ 在“vue-router”中找到

路由器->index.js

import { createWebHistory, createRouter } from "vue-router";
...

const routes = [{
        path: "/user/create",
        name: "createUser",
        component: createUser,
    },
    {
        path: "/users",
        name: "listUser",
        component: listUser,
        meta: { requiresAuth: true }
    },
    {
        path: "/user/show/:id",
        name: "showUser",
        component: showUser,
        meta: { requiresAuth: true }
    },
    {
        path: "/user/update/:id",
        name: "updateUser",
        component: updateUser,
    },
    {
        path: "/login",
        name: "login",
        component: Login
    },
    {
        path: "/register",
        name: "register",
        component: Register
    },
    {
        path: "/users/bearer",
        name: "bearer",
        component: bearer,
        meta: { requiresAuth: true }
    }

]

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

router.beforeEach((to, from, next) => {
    const requiresAuth = to.matched.some(record => record.meta.requiresAuth);
    const isAuthenticated = firebase.auth().currentUser;
    console.log("isauthenticated", isAuthenticated);
    if (requiresAuth && !isAuthenticated) {
        next("/login");
    } else {
        next();
    }
});

export default router;

您需要通过 npm 安装路由器

npm install vue-router@next --save
