Answer 1

您需要在 AppModule（app.module.ts 文件）中添加 Facebook：

// ...
import { Facebook } from '@ionic-native/facebook';


@NgModule({
    declarations: [...],
    imports: [...],
    bootstrap: [IonicApp],
    entryComponents: [...],
    providers: [
        // ...
        Facebook // <--- Here!
        // ...
        { provide: ErrorHandler, useClass: IonicErrorHandler }
    ]
})
export class AppModule { }
