我收到了Angular2教程的下列错误。 TNS医生好，那么为什么会出现下面的错误？

依赖性采样杂货项目的版本即将更新到最新版本NativeScript不过你可以打开你的package.json文件，并更改以下版本：

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

"nativescript-angular": "1.0.0"

"tns-core-modules": "2.3.0"。

您还应该确定hooks,node_modules,platforms文件夹已被删除。关于这一点，在Xcode 8中，现在有些方法是属性，并且在项目中使用本地代码时会导致问题，就像它在样本Groceries中一样。作为临时解决方案，您可以替换status-bar-util.ts和grocery-list.component.ts文件中的一些代码。

应用程序/共享/状态栏-util.ts

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

应用程序/杂货/杂货列表/杂货list.component.ts

cell.backgroundColor = UIColor.clearColor();替换为cell.backgroundColor = UIColor.clearColor;
