Gulp installation error

I'm following the tutorial on installing gulp and i'm on step 7 but when i run the command i get a long error list

$ gulp mdb-go

[10:39:31] Using gulpfile H:\mdbpro\gulpfile.js [10:39:31] Starting 'mdb-go'... [10:39:32] Finished 'mdb-go' after 268 ms events.js:187 throw er; // Unhandled 'error' event ^

Error: UNKNOWN: unknown error, watch at FSEvent.FSWatcher._handle.onchange (internal/fs/watchers.js:125:28) Emitted 'error' event on Domain instance at: at FSWatcher.EventEmitter.emit (domain.js:528:12) at FSWatcher._handleError (H:\mdbpro\node_modules\chokidar\index.js:260:10) at H:\mdbpro\node_modules\chokidar\lib\nodefs-handler.js:55:5 at Array.forEach () at fsWatchBroadcast (H:\mdbpro\node_modules\chokidar\lib\nodefs-handler.js:54:36) at FSWatcher.

and the list goes on for a couple of hundred lines .. what do i need to do to make it start properly?

Before this i had a problem at step 5 with command npm install --save-dev gulp, it did not find the node-sass file for installation but i got it working using a solution from another support topic here using this command $ npm install node-sass@latest but now i'm stuck at step 7.
