i don’t know how to fix these two error ,
i have use losf -i:6600 to see the port ,and the answer is 
Python 77417 wc 12u IPv6 0x5c7a796eb3ce4e6f 0t0 TCP localhost:6600 (LISTEN)
and when i killed it ,it will start again…
You’ve already identified that the server startups fail because you (user wc) are in fact already running Mopidy. Are you also running Mopidy as a system service somehow? Is this a mac?
Ohhhhh， That’s Great!
Thank you very much!
That is really mopidy process and this is a mac…
i am very new so that i have try many ways to use it or install it ,then …it may be changed very confusion.

But how to quit this process ? I can’t kill it
Are you saying that kill 79951 and even kill -9 79951 do not work? If you be helpful if you could be more explicit about exactly what you have tried.
both of them can not be work.
every time when i killed them it will restart
