在Angular | Ionic中没有找到[自定义组件]的组件工厂

Question

我正在将Ionic 3与延迟加载的页面一起使用。 尝试在页面内的组件内显示模式时，出现以下错误：

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

正如你可以看到下面下来，我已经添加了CourseEditorComponent作为entryComponent到courses.modules.ts，其中得到由dashboard.modules.ts进口。

我在Angular / Ionic中使用自定义entryComponents的方式有问题吗？

层次结构

DashboardPage
-CoursesComponent
--CourseEditorComponent
--CourseCreatorComponent
-InstructorsComponent

模组

dashboard.module.ts

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { DashboardPage } from './dashboard';
import { CoursesModule } from "./courses/courses.module";

@NgModule({
  declarations: [
    DashboardPage
  ],
  imports: [
    IonicPageModule.forChild(DashboardPage),
    CoursesModule
  ],
})
export class DashboardPageModule {}

course.module.ts

import { NgModule } from '@angular/core';
import { IonicPageModule } from 'ionic-angular';
import { CoursesComponent } from './courses';
import { CourseEditorComponent } from "./course-editor/course-editor";

@NgModule({
  declarations: [CoursesComponent],
  imports: [IonicPageModule.forChild(DashboardPage)],
  entryComponents: [CourseEditorComponent],
  exports: [CoursesComponent,CourseEditorComponent]
})
export class CoursesModule {}

课程组成

import { Component } from '@angular/core';
import { ModalController } from 'ionic-angular';
import { CourseEditorComponent } from "./course-editor/course-editor";

@Component({
  selector: 'courses',
  templateUrl: 'courses.html',
})
export class CoursesComponent {
  editCourse(data) {
    let editor = this.modal.create(CourseEditorComponent,{course: data});
    editor.present();
  }
}

Answer 1

@NgModule({
  imports:      [ BrowserModule, FormsModule ],
  declarations: [ AppComponent, HelloComponent ],
  bootstrap:    [ AppComponent ],
  entryComponents: [your modal component] // you need to add it to entry component
})
export class AppModule { }

截至目前，没有对它的支持，Angular git repo LINK中报告了相同的问题

使用EntryComponentsModule

导入EntryComponentsModule （在其中定义所有entryComponents）到AppModule直到问题解决。

使用CourseEditorComponent作为页面

将CourseEditorComponent变成页面，然后将modal.create(CourseEditorComponent)更改为modal.create('CourseEditorComponent')

Answer 2

您必须将其添加到声明[]和entryComponents下
