尝试使我的本机脚本应用程序在启用aot的情况下运行。
使用最新版本的nativescript，它的构建就很好。启动应用程序时，错误CREATE TABLE dataHistory (
rowID int identity,
historizationDate datetime default getDate(),
dataID int,
column1 int,
column2 datetime,
...)
出现，并且该应用程序无法运行。
使用依赖于Reflect.getMetadata的依赖项时，例如：https://github.com/ghidoz/angular2-jsonapi
演示项目，使用aot时出错： https://github.com/annervisser/nativescript-aot-error
应用程序使用JIT可以完美运行，并且仅在使用Reflect.getMetadata is not a function标志时才会中断。 Webpack始终处于启用状态，因为这是一个有角度的项目（始终与--env.aot标志一起运行）
完整的堆栈跟踪：
--bundle我尝试在不同的地方导入反射元数据，包括System.err: TypeError: Reflect.getMetadata is not a function

，polyfills.ts，main.tns.ts
我还尝试将其包含在webpack / tnsconfig中，并将目标更改为es2015或es6。
这些都没有任何区别。
搜索该错误会导致产生许多有关角度的常规信息，建议将app.module.tns.ts的导入内容添加到reflect-metadata中。这没有帮助。
答案 0 :(得分：0)
将reflect-metadata包的import语句添加到您的应用模块顶部（基本上在访问JsonApiDatastoreConfig装饰器之前。
import "reflect-metadata";
