File watcher doesn't seem to be working on FreeBSD 11.0

Hello,
I created a simple Angular CLI project in WebStorm and when I make changes to the html/CSS/typescript, the changes are not being made at 'http://localhost:4200'.  In general, after I start the web server (using 'ng serve'), I'll make changes to my html file, type 'Control-s' to save the file (the ability to automatically save after a few milliseconds doesn't seem to exist), and on the first 'Control-S', you can see the web page on 'http://localhost:4200' update to the new changes.  Unfortunately, after the first save, the system fails to keep updating.  What can I do to make the environment to continually update the browser with my changes?
