[SOLVED] Ionic can not find lib directory even though it's there in plain sight

This is a little bizarre and frustrating, but out of nowhere I can’t run Ionic serve because it’s throwing 404 errors on everything in the js/lib directory.

Permissions have not changed, and all the files are physically there. And if I view source in the browser when opening localhost:8100, I can click on any controller.js file, service.js file, html file, etc and those files load in the browser just fine. If I click on a file in the js/lib directory, I get 404 not found.

I tried npm install -g ionic to update… but no luck.

What the heck ??
