### 解决方法: ###

#### 1. 重新创建一个新项目 ####

#### 2. 重新安装依赖. 出现这个问题我是因为我的依赖没有安装好 ####

#### npm install -g vue 安装全局vue ####

#### npm install -g @vue/cli 安装vue脚手架 ，加一个@是最新的版本 ####

#### 3. 修改main.js里面代码 导入包的方式不对 ####

import { createApp } from 'vue'
    import App from './App.vue'
    import router from './router/index'
    
    const app = createApp(App)
    app.use(router).mount('#app')

定义一个变量去存,使用变量去调用
