How To Kill an Open Port Running In React Native (Expo) in Windows

Question

The situation here is that we have initiated a server in React Native using npm start, expo start or other methods and later killed the server using CTRL + C but when you run npm start again you see that the particular port is already being used and it asks if you want to use a different port

Answer 1

i think this would help. Basically try to list the ports in use by :

$ lsof -i :3000 -t
12345

Then,kill the port, usually (pid) :

$ kill 12345

or, if it doesn't work,try this :

$ killall -9 node

Need further help? please do refer to this link: Node.js Port 3000 already in use but it actually isn't?
