下，原来代码编译有问题。 我 修改代码，主要关注功能，供参考

@wpcfan 你好，
我之前都是用jit的那种模式配置，然后我参考你关于aot的说明，在main.ts中改用：

但提示 cannot find module app.module.ngfactory ，请问这个app.module.ngfactory是哪来的呢？还需要怎么配置？
谢谢！

112页倒数第三段最后一行笔误

是不是我的模块改拆分了？

应该为

是不是我的模块该拆分了？

另外有一个问题想请教一下：

如果我使用了 路由 配合 <router-outlet> 是不是 就没法往 里传递 @input 属性了? 比如像这样：

<router-outlet  [var1]="var_a" [var2]="var_b"></router-outlet>

哪怕我能够保证所有插入outlet 的组件 都有 var1 和 var2 的 Input 属性变量。

报错404

依赖包安装后，执行ng serve 后报错，找不到 @angular/animations 模块

我猜应该是因为 animations 从Angular 最新版本的core模块中移除了，代码需要根据具体的Angular 版本改动吧，比如import导入模块语句。

完整的信息，包括ng版本信息，主要是报错信息：

文章中使用 angular2-mdl 产生对话框，可是现在 安装了 angular2-mdl 更本找不到 MdlDialog 这个名字。请问该如何使用？ 谢谢。

之所以提这个是因为我在本地无法运行项目，应该是版本的问题。
你在 readMe.md 文件里的 "环境配置要求" 部分写了 安装ng的命令，但最好补充下安装的ng的版本，比如在文章补充一下 "npm install -g @angular/cli@latest 命令执行后，安装的版本是 2.4.10"，或者命令里指定ng版本

在第二章，建立一个服务去完成业务逻辑 的小节中
ng g s core\auth 应该为
ng g s core/auth

我按照书上的代码敲进去，但是运行的时候报错，求指导。

constructor(private store$: Store<Todo[]>){
...
this.todos = this.store$.select('todos');
}

查看源码发现上面的Store<Todo[]>应该是Store

代码中有：
import 'rxjs/add/operator/toPromise';

但是在代码库中找不到这一行。

教程写的很好，多谢了！

图片里面 angular 2 的组件生命周期函数 组件销毁应是 ngOnDestroy。

正在学习此文，谢谢您的教程。
