问为什么Redis在节点上不起回调作用？

EN

'use strict'
import {createClient} from 'redis';
const redisClient = createClient();

redisClient.on('connect', function() {
    console.log('you are now connected');
});
redisClient.on('ready', function() {
    console.log('you are now ready');
});
redisClient.on('error', function(err) {
    console.log(`redis error: ${err}`)
});

// added for 4.1.0 because there is no autoconnect.
await redisClient.connect();

await redisClient.set("test","value", function(err, reply) {
    console.log('set complete');
});
