I hit the same problem. It is working on my other Ubuntu 16.04 laptop but when I did the following on my Ubuntu 16.04 Mate desktop:

git pull
npm install -g ionic@beta cordova
npm install
ionic serve

Then I get the ENOSPC problem with the watcher. The problem seems to be caused by the watcher exceeding the number of files it can watch. To fix the problem, you need to increase the number of files the OS will allow you to watch. In linux the command is:

echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p

This will resolve the problem

I also got this error when running ionic serve -c -l. However, when I restart--or sometimes when I open a new terminal window--ionic serve will work properly.

the problem is the number of watches .
I resolve with this command : echo fs.inotify.max_user_watches=582222 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
