为什么我没有收到AppModule"的 NgModule 元数据?

Why I am getting No NgModule Metadata for 'AppModule'?

推荐答案

AppModule.ts

AppModule.ts

  , DailyCustomerFeedService,
  , MonthlyCustomerFeedService

在 provider 中添加服务时添加了一个额外的逗号.这让我很沮丧，花了一天的时间来识别它.

There was an extra comma added while adding services inside provider. It frustrated me a lot and took hole day to identify it.
