Gulp either not watching or throwing an error

[jarimbi]

I’m new to Gulp. Just did a project with Roots and Grunt which went without any issues. Now trying out Sage and Gulp. Unfortunately I can’t get it to work.
I followed the instructions: https://roots.io/sage/docs/theme-development/
Everything runs fine, I can run the gulp command and that works without errors.

Then when I do gulp watch it starts and finishes within a minute.
I tried to set up my theme again with fresh installs and then when I run gulp watch it throws the following error:
events.js:72
throw er; // Unhandled ‘error’ event
^
Error: listen EADDRINUSE
at errnoException (net.js:905:11)

I would appreciate some help here. Thanks!

I think you have gulp watch running twice
