Cannot read property 'viewContainerRef' of undefined

You can take this approach:don't create directive, instead give an Id to ng-template

<ng-template #dynamicComponent></ng-template>

use @ViewChild decorator inside your component class

@ViewChild('dynamicComponent', { read: ViewContainerRef }) myRefngAfterViewInit() {    const factory = this.componentFactoryResolver.resolveComponentFactory(component);    const ref = this.myRef.createComponent(factory);    ref.changeDetectorRef.detectChanges();}

I had the same problem. You have to add the directive into the AppModule:

 @NgModule({  declarations: [    AppComponent,    ...,    YourDirective,  ],  imports: [   ...  ],  providers: [...],  bootstrap: [AppComponent],  entryComponents: [components to inject if required]})

In Angular 8 my fix was:

@ViewChild('dynamicComponent', {static: true, read: ViewContainerRef}) container: ViewContainerRef;
