Dears, after I change a line in a file of my Ionic project, my “$ ionic serve” isn’t reloading/rebuilding the application automatically. What is happening? It is occurring after I made it:
Try open ionic serve in a different browser. I had this issue recently, but the issue was isolated to Chrome and fixed it by uninstalling then reinstalling Chrome.
Checking the console ($ ionic serve -c) nothing happens after I made a change in a file of the Ionic project (after saved it).
$ ionic serve -c

Before, the “Development server running!” used to appear again after made a change in a file. I am facing a different problem.
I end up found the solution: just deleted the www directory and after run $ ionic serve -c again, the [app-scripts] [12:14:26] watch ready in 15.68 s turned back appear.
$ ionic serve -c

And another way that I read googling is, when you use linux: $ echo fs.inotify.max_user_watches=524288 | sudo tee -a /etc/sysctl.conf && sudo sysctl -p
