我在 Angular2 教程中遇到以下错误。TNS Doctor 没问题，那么为什么会出现以下错误？

'tns livesync ios --emulator --watch

我正在使用新的 8x Xcode。

sample-Groceries 项目的 Dependences 版本将很快更新到最新的 NativeScript 版本，但是您可以打开 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".

您还应该确保hooks, node_modules,platforms文件夹已被删除。关于这一点，在 Xcode 8 中，一些方法现在是属性，当在项目中使用本机代码时会导致问题，就像在示例杂货店中一样。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;用。。。来代替UIApplication.sharedApplication.statusBarStyle = UIStatusBarStyle.LightContent;

应用程序/杂货/杂货清单/杂货清单.component.ts

cell.backgroundColor = UIColor.clearColor();用。。。来代替cell.backgroundColor = UIColor.clearColor;
