推荐答案
看起来您已经在运行mosquitto代理，并且无法打开端口(因为它们已经打开).
Looks like you already have mosquitto broker running and it's failing to open the ports (beacause they are already open).
这些行表明1883(mqtt端口)已经打开...
Those lines shows that the 1883 (mqtt port) is already open...
TCP 0.0.0.0:1883 0.0.0.0:0 LISTENING
TCP [::]:1883 [::]:0 LISTENING
