【问题描述】：
我正在创建一个 Angular2-Meteor 项目。我已将其设置为使用 Angular 2 RC5。在我尝试使用 @injectable() 装饰器添加服务之前，一切都运行良好。一旦添加，我就会收到流星编译错误：
使用类装饰器时需要反射元数据填充程序
只要我删除了@injectable() 装饰器，Meteor 就会编译所有内容，我可以加载我的应用程序。
我已经安装了 barbatus:angular2-polyfills 包，我认为这是导入所需的 zone.js 和 reflect-metadata 包所需的全部内容。有人建议在 main.ts 顶部使用导入，但这不起作用。
@NgModule 和 @component 装饰器可以正常工作。由于我还没有将服务（使用@injectable 装饰器）连接到我的@ngmodule，我认为这表明Meteor 环境根本没有按预期处理@injectable 装饰器。不管用不用。
任何有关如何解决此问题的建议或想法将不胜感激。
