本地环境将package.json中 "module": "./dist/index.es.js"改为"module": "./dist/index.mjs"
本地打包没问题，部署生产环境时因为重新下载包依然导致报错：

解决方法（自己创建npm包后导入）：

longze-vue3-video-player - npm (npmjs.com)https://www.npmjs.com/package/longze-vue3-video-player

npm i longze-vue3-video-player

import { createApp } from "vue";
import App from "./App.vue";
let app = createApp(App);

import longzeVideoPlay from "longze-vue3-video-player"; // 引入组件
app.use(longzeVideoPlay);

app.mount("#app");

 <longzeVideoPlay
          ref="videoRef"
          :src="testOptions.src"
          :type="testOptions.type"
          :controlBtns="controlBtns"
        />
