"ng2-CKEditor" 节点模块不能与 typescript [Angular2] 一起工作

Question

我正在尝试在我的 angular2 应用程序中配置 CKEditor。我正在使用节点作为我的后端平台，我正在使用 ng2-CKEditor npm 模块。

下面是我在各个文件中的代码。

index.html::

<html>
  <head>

    <!-- 2. Configure SystemJS -->
    <script src="systemjs.config.js"></script>
    <script>
      System.import('app').catch(function(err){ console.error(err); });
    </script>
  </head>
  <!-- 3. Display the application -->
  <body>
    <my-app>Loading...</my-app>
  </body>
</html>

systemjs.config.ts::

/**

(function (global) {
  System.config({
    paths: {
      // paths serve as alias

    },

    },
    // packages tells the System loader how to load when no filename and/or no extension
    packages: {
      app: {
        main: './js/main',
        defaultExtension: 'js'
      },

        main: './index.js',
        defaultExtension: 'js'
      }
    }
  });
})(this);

main.ts::

import {NgModule} from '@angular/core';
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
import {FormsModule} from '@angular/forms';
import {CKEditorModule} from 'ng2-ckeditor';

const platform = platformBrowserDynamic();

@NgModule({
  imports:      [
    CKEditorModule
  ],
  declarations: [
    AppModule,
  ],
  bootstrap: [AppModule]
})
export class AppMain { }

platform.bootstrapModule(AppModule);

app.component.ts::

import { Component } from '@angular/core';
@Component({
  selector: 'my-app', 
  //templateUrl: 'app/templates/write-blog.html'
  template: `
    <ckeditor [(ngModel)]="content" debounce="500">
      <p>Hello <strong>world</strong></p>
    </ckeditor>
    <div [innerHTML]="content"></div>`
})
export class AppComponent { 
   constructor(){
      //this.content = '<p>Hello <strong>World !</strong></p>'
      }
}

app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import {FormsModule} from '@angular/forms';
import {CKEditorModule} from 'ng2-CKEditor'

@NgModule({
  imports:      [ BrowserModule, FormsModule, CKEditorModule],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

错误::

由于我是使用 typescript 的 angular2 的新手并且基本上是 MEAN 堆栈，请帮忙。我检查了其他 post 是否有同样的问题，但没有帮助解决我的问题。

Answer 1

您需要将 FormsModule 添加到模块的 imports 才能使用 ngModel 指令，因为它是 FormsModule:

的一部分

@NgModule({
    imports: [
        CKEditorModule,
        FormsModule
    ]

你的代码也很乱，你应该看看官方Angular 2 quickstart app看看你的代码应该如何组织。
