我正在实现socketjs.然而，我遇到了下面的错误.
x1c 0d1x下面是我正在使用的socket和stomp包。

import * as SockJS from 'sockjs-client';
import * as Stomp from 'stompjs/lib/stomp.js';

字符串
提前致谢。
下面是我的Angular代码-

import * as Socket from 'socket.io-client';
import * as Stomp from 'stompjs/lib/stomp.js';
initializeWebSocketConnection2(){
let ws = new Socket(this.serverUrl);
this.stompClient = Stomp.over(ws);
let that = this;
this.stompClient.connect({}, function(frame) {
   that.stompClient.subscribe("/test", function(message){ 
        if(message.body) {
          console.log(message.body);
         window.location.reload(); 
        }
 });
   that.stompClient.subscribe("/operation", function(message){ 
        if(message.body) {
          console.log(message.body);
          window.location.reload();
        }
 });
