Current behavior:

1. updated ionic cli to 3.20.0 from 3.19.1
2. import {TranslateService} from '@ngx-translate/core'; ngx-translate/core package went missing, npm install fixed this package issue
3. ionic serve worked
4. got a run time error:

Error Runtime Error Object(...) is not a function
Expected behavior:

After upgrade, there shouldn't be a runtime error;

Ionic info: (run ionic info from a terminal/cmd prompt and paste output below):

What version of the the ngx-translate/core are you using?
Version 10 and up have breaking changes. (https://github.com/ngx-translate/core/releases)
And since Ionic is not yet supporting angular 6 you need to stay at version 9.1.1 for the core and 2.0.1 for the HTTP-loader and if you use the rxjs library as well keep that on 5.5.0

I imported angular translate into each submodules and it works now.

Thanks for helping!
