build ionic2 Anwendung konnte nicht

Question

ich meine erste App haben hier in Github: https://github.com/eshk12/firstApp

ich versuche, es zu APK-Datei zu erstellen, aber es ist fehlgeschlagen. Ich habe Android SDK installieren und Android-Plattform zum Projekt hinzufügen.

aber ich bekomme diese Fehler, ich habe keine Ahnung, was das Problem ist.

In Ihrem view Sie verwenden eine Eigenschaft namens selectCurrencyInput

<ion-select okText="אשר" cancelText="בטל" [(ngModel)]="selectCurrencyInput">

aber es ist nicht in Ihrem component code erklärt.

@Component({ 
    selector: 'currency-page', 
    templateUrl: 'currency.html', 
    providers: [NetworkServices] 
}) 
export class CurrencyPage { 
    public load: any; 
    public results: any; 
    public amount: any; 
    public keys: any; 

    public selectCurrencyInput: string; // <- add this property to fix the issue 

    constructor(public networkServices: NetworkServices) { 
    this.load = false; 
    } 

    // ... 
}
