在尝试解决这个问题的过程中，我看到了很多不恰当的答案.普遍的反应是您正在尝试停止尚未启动的程序"或其他程序正在您需要的端口上运行".

I've seen a lot of inadequate answers while trying to figure this one out. General response has been "you are trying to stop something that hasn't started" or "some other program is running on the port you need".

我的问题原来是我的防火墙.我什至没有考虑过这个，但是端口 8005(用于关闭的端口，感谢 Mindas)被阻止了.我改变了它，现在，没有更多的错误.祝你好运.

The problem for me turned out to be my firewall. I hadn't even considered this, but port 8005 (the port used for shutdown, thanks mindas), was blocked. I changed it, and now, no more error. Good luck.
