角4:找不到组件工厂，您是否将其添加到@ NgModule.entryComponents? [英] Angular 4: no component factory found,did you add it to @NgModule.entryComponents?

问题描述

我正在将Angular 4模板与webpack一起使用 当我尝试使用组件(ConfirmComponent)时出现此错误:

I'm using Angular 4 template with webpack and I have this error when I try to use a component (ConfirmComponent):

没有为ConfirmComponent找到组件工厂.您是否将其添加到 @ NgModule.entryComponents?

No component factory found for ConfirmComponent. Did you add it to @NgModule.entryComponents?

该组件在app.module.server.ts

@NgModule({
  bootstrap: [ AppComponent ],
  imports: [
    // ...
  ],
  entryComponents: [
    ConfirmComponent,
  ],
})
export class AppModule { }

我也有app.module.browser.ts和app.module.shared.ts

我该如何解决?

推荐答案

将此添加到您的module.ts，

declarations: [
  AppComponent,
  ConfirmComponent
]

如果ConfirmComponent在另一个模块中，则需要将其导出，以便可以在外部使用，请添加:

if ConfirmComponent is in another module, you need to export it there thus you can use it outside, add:

exports: [ ConfirmComponent ]

---显式启用Ivy更新Angular 9或Angular 8 ---

不再需要带有常春藤的条目组件，现在已弃用

---用于禁用了Ivy的Angular 9和8 ---

对于动态加载的组件，要生成ComponentFactory，还必须将该组件添加到模块的entryComponents中:

In the case of a dynamically loaded component and in order for a ComponentFactory to be generated, the component must also be added to the module’s entryComponents:

declarations: [
  AppComponent,
  ConfirmComponent
],
entryComponents: [ConfirmComponent],

根据entryComponents的定义

according to the definition of entryComponents

指定在定义此模块时应编译的组件列表.对于此处列出的每个组件，Angular将创建一个ComponentFactory并将其存储在ComponentFactoryResolver中.

Specifies a list of components that should be compiled when this module is defined. For each component listed here, Angular will create a ComponentFactory and store it in the ComponentFactoryResolver.
