primeng/panel gives Ivy error on Angular 9.0.2 and PrimeNG 9.0.0

import { PanelModule } from 'primeng/panel';


@NgModule({
  declarations: [
    AppComponent,
    RegionsComponent,
    HomeComponent,
    CountryDetailsComponent
  ],
  imports: [
    BrowserModule,
    BrowserAnimationsModule,
    HttpClientModule,
    AppRoutingModule,
    NgbModule,
    DropdownModule,
    PanelModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Error message:-

95% emitting CopyPlugin    
    ERROR in node_modules/primeng/panel/panel.d.ts:30:22 - error NG6002: Appears in the NgModule.imports of AppModule, but could not be resolved to an NgModule class.

    This likely means that the library (primeng/panel) which declares PanelModule has not been processed correctly by ngcc, or is not compatible with Angular Ivy. Check if a newer version of the library is available, and update if so. Also consider checking with the library's authors to see if the library is expected to be compatible with Ivy.

    30 export declare class PanelModule {

I'm unable to replicate, the panel worked fine when ivy is on. If the issue persists, please create a new issue ticket and refer to a sample project that replicates the issue e.g. stackblitz or a github repo.

remove node_models and npm install again - that fixed it for me
