angular2使用嵌套导入模块的组件

Question

is it possible to have the following strucure? 有没有可能有以下结构？

app.component.js app.component.js

@Component({
    template: '<nav-context></nav-context>'
class AppComponent

app.module.js app.module.js

@NgModule({
    imports: [CoreModule]
    boostrap: [AppComponent]

core.module.js core.module.js

@NgModule({
    imports: [NavModule]
class CoreModule

nav.module.js nav.module.js

@NgModule({
    declarations: [NavContextComponent]
    exports: [NavContextComponent]
class NavModule

nav-context.component.js NAV-context.component.js

@Component({
    selector: 'nav-context'
class NavContextComponent

So far I get 'nav-context' is not a known element 到目前为止，我得到的'nav-context' is not a known element

I think you need to also export the module if you want it to be provided to importers 如果您希望将模块提供给导入器，我认为您还需要导出模块

@NgModule({
    imports: [NavModule]
    exports: [NavModule]
