问题描述
我有一个大约在2015年左右开发的应用，急需升级。我尝试按照https://docs.nativescript.org/releases/upgrade-instructions上的升级说明进行操作，并且在使编译器无法正常工作之后，我现在遇到了一堆错误，就像Angular无法加载应用程序一样。
我正在与更广泛的社区联系，以查看是否有人在2015年做了类似的事情，或者是否有其他指导方针来升级使用Angular构建的旧NativeScript应用。
欢迎任何建议：-）

解决方法
前三个系统错误行指向（初始？）线索：
System.err: An uncaught Exception occurred on "main" thread.
System.err: Unable to create application com.tns.NativeScriptApplication:com.tns.NativeScriptException: Error calling module function
System.err: TypeError: application.start is not a function
我猜在您的入口点文件（main.ts？）中，导入对NS7不正确。
