How to kill already in use port in React Native?

It shows this error

error listen EADDRINUSE: address already in use :::8081. Error: listen EADDRINUSE: address already in use :::8081

Things i have tried

kill -9, killall node, adb reconnect etc nothing works it again shows same error when npm start

Solution 

  •    Im using Linux Try This !
        find which PID is using ur Port{8081} by following command
    sudo lsof -i :8081

    Output something like this:
     COMMAND  PID     USER     FD    TYPE DEVICE SIZE/OFF NODE NAME
              node    7689   kishan   23u  IPv6  65425      0t0  TCP *:tproxy (LISTEN)
              
    then fire this command to kill server 

    syntax:- kill -9 USER

    eg:
    kill -9 7689
