Running grunt serve on Linux creates an endless loop:
grunt serve
$ grunt serve Running "watch" task Waiting... Warning: watch ENOSPC Running "watch" task Waiting... Warning: watch ENOSPC ...
Look for suggestions to make it work.
Try this command:
echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
It should work.
