我在我的服务器文件中只有这个,并出现错误:

const WebSocket = require('ws');

const wss = new WebSocket.Server({ port: 9000 });

wss.broadcast = function broadcast(data) {
  wss.clients.forEach(function each(client) {
    if (client.readyState === WebSocket.OPEN) {
      client.send(data);
  }
});
};

wss.on('connection', function connection(ws) {
    ws.on('message', function incoming(data) {
        wss.broadcast(data);
    });
});

终端显示此错误:

/home/mgmaip/server/node_modules/ws/lib/PerMessageDeflate.js:8
const TRAILER = Buffer.from([0x00, 0x00, 0xff, 0xff]);
                       ^
