Question

我正在尝试使用AngularJS 2构建一个简单的表单，遵循快速入门指南（https://angular.io/docs/ts/latest/guide/forms.html）中的示例。
当我按照bootstrap（）函数中的建议禁用旧表单模块并启用新表单模块时，我收到编译错误。

我对AngularJs很新。任何帮助表示赞赏。详情如下：

在向引导函数添加“[disableDeprecatedForms（），provideForms（）]”时，会引发编译错误。

以下是main.ts文件中的代码。

import { bootstrap }    from '@angular/platform-browser-dynamic';
import { disableDeprecatedForms, provideForms } from '@angular/forms';
import { AppComponent } from './app.component';

bootstrap(AppComponent,[ appRouterProviders ], [ 
                                           disableDeprecatedForms(), 
				       provideForms() 
				       ] );
/*
bootstrap(AppComponent,[ appRouterProviders ] );
*/

如果我在main.ts中有上面的代码时，“npm start”正在转换，我得到以下编译错误。

如果我使用注释中显示的bootstrap（）调用，它会编译没有错误，但会发出警告“*看起来你正在使用旧的表单模块....”

[0] app/main.ts(7,1): error TS2346: Supplied parameters do not match any signature of call target.
[0] 9:24:40 PM - Compilation complete. Watching for file changes.

如果我用main.ts中的这段代码启动“npm start”，npm只是拒绝启动并抛出ERR！。以下是npm-debug.log的摘录：

这样做删除括号[]

import { bootstrap }    from '@angular/platform-browser-dynamic';
import { disableDeprecatedForms, provideForms } from '@angular/forms';
import { AppComponent } from './app.component';

bootstrap(AppComponent, [ 
    appRouterProviders,  
    disableDeprecatedForms(), 
    provideForms()
]);

在bootstrap（）中使用[disableDeprecatedForms（），provideForms（）]时，Angular2表单编译错误
