ionic-framework - push and setRoot to one page in ionic 3

Question

I am getting below error when setting Rootpage in ionic 3.

 Error: No component factory found for LoginPage. Did you add it to 
 @NgModule.entryComponents?

but when I add this page into aap.module.ts in declaration and entrypoint section, this error is gone for setRoot but not for push. When I push, it is not working.

I guess that means I can do either setRoot or push to a one page in ionic 3?
