?解決方法:?
1. 重新創(chuàng)建一個(gè)新項(xiàng)目
2. 重新安裝依賴. 出現(xiàn)這個(gè)問題我是因?yàn)槲业囊蕾嚊]有安裝好
npm install -g vue 安裝全局vue
npm install -g @vue/cli 安裝vue腳手架 ，加一個(gè)@是最新的版本
3. 修改main.js里面代碼? ?導(dǎo)入包的方式不對(duì)
import { createApp } from 'vue'
import App from './App.vue'
import router from './router/index'
const app = createApp(App)
app.use(router).mount('#app')
定義一個(gè)變量去存,使用變量去調(diào)用文章來源地址http://www.zghlxwxcb.cn/news/detail-435945.html
