Angular 7: Cant' resolve core-js/features/object/keys

Question

In my project, I am using the ngx-toaster for the alert/warning/error messages, but when I checked on IE9,10,11 the toaster is not displaying

As a workaround from this thread https://github.com/scttcper/ngx-toastr/issues/673

i've imported

import 'core-js/features/object/keys';

But this throws the following error

Cant' resolve core-js/features/object/keys

However this import 'core-js/es6/object' is actually a valid import

core-js version: 2.5.4

Answer 1

If you check the docs for core-js@2 , you'll see that core-js/features/object/keys is not present.

Version 2 docs: https://github.com/zloirock/core-js/tree/v2

I think the import you're looking for in version 2 is core-js(/library)/fn/object/keys
