Angular 6中的两个具有公共组件的延迟加载模块

Question

我有一个像

---app.module
-------child1.module
-------child2.module

并且我app-film在两个子模块中都使用了1个公共组件（），我在中声明了一个app.module，但是Angular仍然显示错误

Can't bind to 'film' since it isn't a known property of 'app-film'.
1. If 'app-film' is an Angular component and it has 'film' input, then verify that it is part of this module.
2. If 'app-film' is a Web Component then add 'CUSTOM_ELEMENTS_SCHEMA' to the '@NgModule.schemas' of this component to suppress this message.

Answer 1

嵌套模块将看不到在父模块（导入嵌套模块）中定义的组件。你需要创建一个SharedModule这样的

@NgModule({
   declarations: [ AppFilmComponent ]
   exports: [ AppFilmComponent ]
})
export class SharedModule { }

AppFilmComponent从该模块导出，然后将SharedModule模块分别导入到两个子模块中。

@NgModule({
   ...
   imports: [ SharedModule ]
   ...
})
export class Child1Module { }

和

@NgModule({
   ...
   imports: [ SharedModule ]
   ...
})
export class Child2Module { }
