如果有遇到报错：TypeError: interactor.init is not a function

请把tsparticles版本降到2.12.0

npm i tsparticles@2.12.0

注意：这个vue3-particles和particles.vue3有些许差别的（安装、引入方式）

particles.vue3示例：vue3 使用particles插件粒子_vueparticles_余温无痕的博客-CSDN博客

下面是vue3-particles使用介绍

先看效果，背景图是自己设置的

安装：

// 这两个都要安装

npm i vue3-particles

npm i tsparticles@2.12.0  // 不要3版本以上，会报错TypeError: interactor.init is not a function

 在main.js中引用

import Particles from "vue3-particles"

const app = createApp(App);
app.use(Particles).mount("#app")

页面上，更新了放置背景图片的css

<template>
    <div class="login-bg">
        <vue-particles id="tsparticles" :particlesInit="particlesInit" :particlesLoaded="particlesLoaded" :options="data.options" />
    </div>
</template>
