ngx-lightbox not working with Angular 7

[imrahulmpawar]

Hi,
I installed ngx-lightbox as per the instruction listed here.
also,Included the style css line in angular.jon.

Then setup the project as mentioned here.

Now in my custom component class following line fails :

export class LightboxComponent
{
  _albums: Array;
  constructor(private _lightbox: Lightbox) <====
  {

Coz nothing gets rendered on chrome and i get following error on console :

Uncaught Error: Can't resolve all parameters for Lightbox: ([object Object], [object Object], [object Object], [object Object], [object Object], ?).

Kindly help resolve this.

Is this below code missing a "@Injectable" ?

@Injectable <==== ?
export declare class Lightbox {
    private _componentFactoryResolver;
    private _injector;
    private _applicationRef;
    private _lightboxConfig;
    private _lightboxEvent;
    private _documentRef;
    constructor(_componentFactoryResolver: ComponentFactoryResolver, _injector: Injector, _applicationRef: ApplicationRef, _lightboxConfig: LightboxConfig, _lightboxEvent: LightboxEvent, _documentRef: any);
    open(album: Array, curIndex?: number, options?: {}): void;
    close(): void;
    _createComponent(ComponentClass: any): ComponentRef;
}

This got resolved !
Not sure how/why but i did following :

npm install [email protected]

even though the installation page said to use [email protected] for angular 7 as mentioned here.
