Cannot read properties of undefined (reading ‘use‘)-------编程版本问题

简介: Cannot read properties of undefined (reading ‘use‘)-------编程版本问题

大家好,我是爱你三千遍斯塔克,有时我们在敲代码的时候,可能会碰到这样的问题,Cannot read properties of undefined (reading 'use'),这句代码的意思是无法读取未定义的属性(读取“use”),那么如何解决呢?,这里有一些参考方法,可供大家进行参考,希望对大家有帮助。

2、在vue3的版本,只能安装并使用vue-router4.x

npm i vue-router@next -S

3、Vue-router按需导入方法

4、index.js写法

import { createRouter, createWebHashHistory } from "vue-router"
const router = createRouter({
    history: createWebHashHistory(),
    routes: [
    ]
})
export default router

5、main.js写法

import { createApp } from 'vue'
import App from './App.vue'
import lingyiHeader from '@/components/lingyiHeader.vue'
import router from '@/router/index.js'
import "@/css/common.css"
Vue.component('lingyiHeader', lingyiHeader)
const app = createApp(App)
app.use(router)
app.mount('#app')

6、修正完毕
