Question

所以经过多次与版本的斗争，我有一个新的angular-cli启动应用程序，按照Angular2材料自述完成所有内容，得到按钮和卡片加载和编译，我的应用程序仍然正确加载。

然后我在我的组件中添加了一个导入MdSidenavModule，一切都很好。在我的app.module文件的顶部，我然后调用MdSidenavModule的导入，并在@NgModule中我将MdSidenavModule添加到导入部分，就像我对按钮和卡片所做的那样。除非我这样做并保存，我的应用程序编译正确，但它永远不会离开“正在加载...”并进入我应该打印“应用程序工作！”的组件。就像默认的angular-cli app一样。

非常感谢任何帮助！

进入控制台的错误是

这是我的app.module.ts

import { NgModule }      from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MdCardModule } from '@angular2-material/card';
import { MdButtonModule } from '@angular2-material/button';
import { MdSidenavModule } from '@angular2-material/sidenav';
import { AppComponent }  from './app.component';

@NgModule({
  imports:      [ BrowserModule, MdButtonModule, MdCardModule, MdSidenavModule],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

我的app.component.ts

import { Component } from '@angular/core';
import { MdCardModule } from '@angular2-material/card';
import { MdButtonModule } from '@angular2-material/button';
import { MdSidenavModule } from '@angular2-material/sidenav';
@Component({
  moduleId: module.id,
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css']
})
export class AppComponent {
  title = 'app works!';
}

我已经安装了双重检查并且安装了sidenav，但我也重新安装了它以确保安装。不确定我遗失了什么。

我很笨，我忘了把它添加到materialPkgs数组中来加载。
