Dependency injection 角度5中的Outlook加载项：Can'；t解析组件的所有参数

我正在使用Angular 5创建Outlook加载项。我使用Yeoman生成文件，而不是angular cli。我有一个我编写的服务，MeetingsService，我正试图将它注入到我的一个组件BehaviorSearchComponent中。我在AppModule中将我的服务列为提供者，并将其导入BehaviorSearchComponent。当我运行外接程序时，我得到了错误信息

Can't resolve all parameters for BehaviorsSearchComponent: (?)

如果我这样做，它会起作用

constructor (@Inject(MeetingsService) meetingsService: MeetingsService)

但我希望不用@Inject就可以做到这一点。我还尝试在我的taskpane.ts文件中导入core js/es7/reflect，它是我的根文件。我检查了我的webpack.config，为我的条目polyfill指定了babel/polyfill。我不认为这是一个循环依赖的问题；我安装了该软件包，但在构建过程中没有收到任何警告

有什么我遗漏的吗？我的package.lock.json中的依赖项是否存在问题？我的@angular软件包是5.2.11或5.2.5

作为

构造函数注入（@Inject（MeetingsService）MeetingsService:MeetingsService）

似乎是唯一的方法，因为使用Yeoman（

yo office

）生成的项目使用webpack而不是Angular CLI
