VUE前端页面打开阿里云播放器报错Aliplayer is not defined

前端大哥帮个忙看看，VUE页面实现阿里云播放器，加载的时候报错找不到阿里云播放器对象Aliplayer is not defined； 加载顺序不对哦？

import { getPlayAuth } from "@/api/getData.js";
export default {

    methods:{
            //获取视频详情
            async initParam(vid){
                try{
                  const result =  await getPlayAuth(vid)
                 // console.log("result:"+result.data.data) //拿到播放凭证
                  //////////////打开阿里云播放器///////////
