React- Native by Intellij IDEA

Question

How can I run React-Native apps by Intellij IDEA.

Metro Bundler can't listen on port 8081

when I change port, the same error given

Answer 1

If you are really changing the port, you shouldn't receive the same error. This error generally happens because there is a process already running on this door, if you are using Linux, try fuser -k 8081/tcp, that will kill the process running on that door.

Answer 2

in my case, just remove the 'start React Native Bundler' before launch task.

some other script will start the bundler too, so 8081 port is in use.
