I'm getting an unhandled error when trying to run node server

So, I'm really new to node and I feel like this might be something very simple but I can't figure it out. I installed the dependencies but when I try to start the server by doing "node server" I get this error: 

Vladimirs-MBP:comeat-server Vladimir$ node server
events.js:183
      throw er; // Unhandled 'error' event
      ^

Error: listen EADDRNOTAVAIL 18.194.133.202:3001
    at Object._errnoException (util.js:1022:11)
    at _exceptionWithHostPort (util.js:1044:20)
    at Server.setupListenHandle [as _listen2] (net.js:1350:19)
    at listenInCluster (net.js:1408:12)
    at GetAddrInfoReqWrap.doListen [as callback] (net.js:1517:7)
    at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:97:10)

Your 3001 port is already used by some service, please change the port 

var http = require('http');

//create a server object:
http.createServer(function (req, res) {
  res.write('Hello World!'); //write a response to the client
  res.end(); 
}).listen(8080); //the server object listens on port 8080

You can use these commands to check what ports are being used:

 1. sudo lsof -i -P -n | grep LISTEN
 2. netstat -tulpn | grep LISTEN

You can kill that process number using

sudo kill -9 process_number

Your 3001 port is in use. you should use another port or kill 3001 port and then use it.

for example

sudo kill -9 $(sudo lsof -t -i:3001)
