它工作得非常好，突然它在运行ng服务时开始给我以下异常。我没有做任何最近的升级或依赖添加的东西。
有人可以帮我解决应该采取的措施吗？

我卸载，安装并再次尝试，但没有运气。尝试使用最新的打字稿版本，但获得了一些其他例外，因此还原了这些更改。
答案 0 :(得分：0)
我犯了一个非常愚蠢的错误，NgModule也加入了进口。我刚删除它然后解决了这个问题。

已解决的代码:(从导入中删除了NgModule）
import { NgModule } from '@angular/core';
import { AddBannerComponent } from './add-banner/add-banner.component';
import { BannerComponent } from './banner.component';
import { BannerRoutingModule } from './banner-routing.module';
@NgModule({
imports:[NgModule,BannerRoutingModule],
declarations:[AddBannerComponent,BannerComponent],
providers:[]
})
export class BannerModule{
