Ionic Serve not working on ionic CLI 3.16

Ionic Framework ionic-v3
1

Hi,

I want to run my code on Ionic DevApp.

Ionic serve not working on ionic CLI 3.16. Ionic stops after completing the query.

Ionic starts working when I run code npm run ionic:serve or npm run ionic:serve --verbose

but I want to run my code on DevApp but it will only work when ionic serve will run.

Here is the ionic serve result:

$ ionic serve
