Nativescript Angular2教程導致錯誤

Question

我收到了Angular2教程的下列錯誤。 TNS醫生好，那麼爲什麼會出現下面的錯誤？

'tns livesync ios --emulator --watch

我正在使用新的8x Xcode。

依賴性採樣雜貨項目的版本即將更新到最新版本NativeScript不過你可以打開你的package.json文件，並更改以下版本：

tns-ios": {"version": "2.3.0"}

"nativescript-angular": "1.0.0"

"tns-core-modules": "2.3.0"。

您還應該確定hooks,node_modules,platforms文件夾已被刪除。關於這一點，在Xcode 8中，現在有些方法是屬性，並且在項目中使用本地代碼時會導致問題，就像它在樣本Groceries中一樣。作爲臨時解決方案，您可以替換status-bar-util.ts和grocery-list.component.ts文件中的一些代碼。

應用程序/共享/狀態欄-util.ts

UIApplication.sharedApplication().statusBarStyle = UIStatusBarStyle.LightContent;替換UIApplication.sharedApplication.statusBarStyle = UIStatusBarStyle.LightContent;

應用程序/雜貨/雜貨列表/雜貨list.component.ts

cell.backgroundColor = UIColor.clearColor();替換爲cell.backgroundColor = UIColor.clearColor;
