2. 创建配置文件 options.ts

// 在 utils 文件夹中 创建options.ts
export const options = {

二、修改文件中代码

1. 在 main.ts 中引入插件

import { createApp } from 'vue'
import './style.css'
import 'animate.css';
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import Particles from "vue3-particles";// 引入插件
import App from './App.vue'
const app = createApp(App)

app.use(Particles)
app.use(ElementPlus, { size: 'small', zIndex: 3000 })
app.mount('#app')

2. 在App.vue 中使用插件

<template>
