Question

我有一个共享模块，希望在新的Angular应用中使用。该共享使用了一个简单的服务，该服务执行发布请求，并且还包含来自同一共享模块的一组其他组件。

在我的新AppModule中导入模块，会产生以下错误：

  StaticInjectorError(Platform: core)[UpgradeModule -> Injector]: 
    NullInjectorError: No provider for Injector!
    at NullInjector.push../node_modules/@angular/core/fesm5/core.js.NullInjector.get (core.js:8895)
    at resolveToken (core.js:9140)
    at tryResolveToken (core.js:9084)
    at StaticInjector.push../node_modules/@angular/core/fesm5/core.js.StaticInjector.get (core.js:8981)
    at resolveToken (core.js:9140)
    at tryResolveToken (core.js:9084)
    at StaticInjector.push../node_modules/@angular/core/fesm5/core.js.StaticInjector.get (core.js:8981)
    at resolveNgModuleDep (core.js:21217)
    at _createClass (core.js:21264)
    at _createProviderInstance (core.js:21234)

我感觉共享模块有问题，有人可以帮助我了解我的错吗？谢谢

我的“共享模块”

@NgModule({
    declarations: [MyListComponent],
    exports: [MyListComponent],
    bootstrap: [MyListComponent],
    imports: [
        CommonModule, TranslateModule, FormsModule, NgbModule, SomeModule1, SomeModule2
    ],
    providers: [MyListService]
})
export class MyListModule {
}

我的AppModule：

@NgModule({
    declarations: [
        AppComponent
    ],
    imports: [
        BrowserModule,
                CommonModule,
        MyListWrapperModule

    ],
    providers: [

    ],
    bootstrap: [AppComponent],
})
export class AppModule { }

我的包装器模块：

@NgModule({
    declarations: [MyListWrapperComponent],
    imports: [MyListModule],
    exports: [MyListWrapperComponent]
})
export class MyListWrapperModule {
}

StaticInjectorError（AppModule）[UpgradeModule->注入器]
