Node.js Question

ERROR: open:src: None-Zero Exit(1)

I'm playing with a React/Redux app using Visual Studio Code and Express as my dev server.

Everything was working fine until I killed my terminal to run a new

npm start -s
command and started getting the following error. Anyone has any idea what this is about?

throw er; // Unhandled 'error' event

Error: listen EADDRINUSE :::3000

I think your server did not close properly you need to close the server manually. If you are on a unix system try

ps aux | grep node

to get the process ids.

and then:

kill -9 PID

-9 on kill sends a SIGKILL

If on windows you can try to Run cmd.exe as 'Administrator':

C:\Windows\System32>taskkill /F /IM node.exe
