npm install element-plus --save
在 main.js 中写入以下内容：
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)
app.mount('#app')
引入部分组件
import { createApp } from 'vue'
import { ElButton, ElSelect } from 'element-plus';
import App from './App.vue';
const app = createApp(App)
app.component(ElButton.name, ElButton);
app.component(ElSelect.name, ElSelect);
/* or
 * app.use(ElButton)
 * app.use(ElSelect)
 */
app.mount('#app')
