我有这样的代码

const redis = require("redis");
const client = redis.createClient();

client.on("connect", function() {
  console.log("You are now connected");
});

client.set("student", "Laylaa", function(err, reply) {
  console.log(reply);
});

但是有这样一个错误。。
events.js:291抛出器；//未处理的“错误”事件^
错误：tcpconnectwrap.afterconnect[as oncomplete]（net.js:1145:16）处的connect econnrefused 127.0.0.1:6379在redisclient.on处的redisclient示例上发出“error”事件\u socket处的错误（e:\teknik informatika\latihan redis\node\modules\redis\index.js:341:14）(e:\teknik informatika\latihan redis\node\u modules\redis\index.js:222:14）

有解决办法吗？谢谢
