I am trying to start React Js server by using command "npm start" but it is showing following error on console:

prateek@localhost:~/WebstormProjects/untitled> npm start

> untitled@0.1.0 start /home/prateek/WebstormProjects/untitled
> react-scripts start

Could not find an open port at localhost.localdomain.
Network error message: getaddrinfo ENOTFOUND localhost.localdomain

npm ERR! code ELIFECYCLE

npm ERR! This is probably not a problem with npm. There is likely additional logging output     above.

npm ERR! A complete log of this run can be found in:

I am using npm 5.3.0 and node 8.4.0 on Linux.

on OpenSUSE, To fix getaddrinfo ENOTFOUND localhost.localdomain error issue, you can try:

Verify that the HOST environment variable is set correctly. You can run echo $HOST to see its current value. If the value is incorrect or missing, you can set it by running export HOST=localhost in your terminal.

It appears like something else is running on the development port for react (port 3000). Run the command sudo lsof -n -i :3000 | grep LISTEN and then either close the program that is using the port or use sudo kill {PID} (replace {PID} with the PID found using the first command).
