Vue路由的使用中：uncaught typeerror: cannot use ‘in‘ operator to search for ‘path‘ in undefined

uncaught typeerror: cannot use ‘in’ operator to search for ‘path’ in undefined问题解决

主要是问题在router.js 中个人代码不熟悉

import {createRouter,createWebHistory} from 'vue-router'
import loginVue from '@/views/login.vue'
import layoutVue from '@/views/layout.vue'

const routes = [
    {path: '/login',component: loginVue},
        // 默认是login
    {path: '',redirect: '/login'},
    {path: '/layout',component: layoutVue}
]
// 创建路由器
const router =createRouter({
    history:createWebHistory(),
    routes:routes
})

export default  router

如果这里的代码没有加上括号，就会报错。

history:createWebHistory()//正确写法
history:createWebHistory//个人报错的写法
