 Error: listen EADDRINUSE :::5858 at Object.exports._errnoException (util.js:1018:11) at exports._exceptionWithHostPort (util.js:1041:20) at Agent.Server._listen2 (net.js:1258:14) at listen (net.js:1294:10) at net.js:1404:9 at _combinedTickCallback (internal/process/next_tick.js:83:11) at process._tickCallback (internal/process/next_tick.js:104:9) [19:59:20] [nodemon] watching 174 files 

Answer 1

It's is probably running in the background or some other process maybe bound to the port,

try following command,

netstat -tulpn

get the pid of the process bound to the port and kill it using

kill <pid>

try the first command again if it's still there try,

kill -KILL <pid>

And try running again
