一、vue3 创立我的项目下载 element 依赖报错 npm ERR code ERESOLVE
PS C:\Users\PC\Desktop\ 我的项目 \toutiao-publish-admin> npm i element-ui -S
npm ERR! code ERESOLVE

解决：重复下载依赖报错，应该是 npm 版本的问题
npm i element-ui -S --legacy-peer-deps
vue3 中引入 elementUI，和 vue2 不同
vue add element-plus
import {createApp} from 'vue'
import ElementPlus from 'element-plus';
import 'element-plus/lib/theme-chalk/index.css';
import App from './App.vue';
const app = createApp(App)
app.use(ElementPlus)应用和和 element-ui 一样
