The problem here is Error: listen EADDRINUSE 0.0.0.0:3000
You already have a process connected to port 3000, so do you have another node.js service running?

[webmobiles]

yes; you are right, was another service in that port , was nice if the error is an english phrase

[ghost]

hmm, @markstrefford
instead of using another port, how can I do if I have to use the original port number?
At the above example, I'm gonna use port 3000. In this case, how can I manage this problem?

Thanks,
Alex

thanks @markstrefford , i was too facing the same problem and your suggestion helped me in resolving it.

[vvp45]

the same error occurred in my program,
how can I fix it?
I try it changing the port number, but not solved.
Please anyone tell me.
