Hi,
I have insalled ng2-ckeditor using cli :- npm install ng2-ckeditor --save
Then Include CKEditor javascript files in my index file :- <script src="https://cdn.ckeditor.com/4.5.11/full/ckeditor.js"></script>
Then imported module in module file:
import { CKEditorModule } from 'ng2-ckeditor';
in imports "CKEditorModule"

and trying to use in html
<ckeditor [formControl]="description" [config]="config" >

It show error:
