UIMain屏幕不是函数错误NativeScript iOS

我正在尝试在iOS模拟器上运行我的NativeScript应用程序。由于iTunes希望应用程序通过Xcode 9.0或更高版本发布，我不得不从使用Xcode 7.3的NativeScript iOS v3.1（我的应用程序运行得非常好）升级到使用Xcode 9.0的NativeScript iOS v4.2。现在很遗憾，我无法在任何设备上执行我的应用程序。它一路启动，我看到加载屏幕，然后遇到以下错误：

CONSOLE ERROR file:///app/tns_modules/zone.js/dist/zone-node.js:419:27: Unhandled Promise rejection: UIScreen.mainScreen is not a function. (In 'UIScreen.mainScreen()', 'UIScreen.mainScreen' is an instance of UIScreen) ; Zone: angular ; Task: Promise.then ; Value: TypeError: UIScreen.mainScreen is not a function. (In 'UIScreen.mainScreen()', 'UIScreen.mainScreen' is an instance of UIScreen)
CONSOLE ERROR file:///app/tns_modules/zone.js/dist/zone-node.js:421:23: Error: Uncaught (in promise): TypeError: UIScreen.mainScreen is not a function. (In 'UIScreen.mainScreen()', 'UIScreen.mainScreen' is an instance of UIScreen)

当我回到使用NativeScript iOS 3.1.0的Xcode 7.3时，它又能正常工作了。我不知道我能做些什么来解决这个问题

我看到了一些与UIScreen.main屏幕错误相关的问题（例如），但它们似乎是与本机iOS相关的，我无法从NativeScript中影响它们（至少我不知道如何才能做到）

下面是我的配置中的一些内容：

问题在于，您的

tns核心模块

是一个较旧的版本（大约2年前），并且正在使用已经弃用的iOS API，其中

主屏幕

是一个函数（现在它是一个属性）。您只更新了使用新ios API的tns ios运行时，而旧

tns核心模块中的代码使用旧API。总之，这是行不通的，您必须更新
tns核心模块
和
nativescript angular
+所有相关依赖项。您可能还需要到处更新代码隐藏文件

可以找到
包/json
依赖项的升级说明

中断从2.x.x迁移时需要考虑的更改

参见
tns核心模块的变更日志

最后，可以找到
nativescript angular
的变更日志
