Angular和Typescript:不能找到名字——错误:不能找到名字

我使用Angular(版本2)和TypeScript(版本1.6)，当我编译代码时，我得到这些错误:

这是代码:

import 'reflect-metadata';
import {bootstrap, Component, CORE_DIRECTIVES, FORM_DIRECTIVES} from 'angular2/core';
@Component({
  selector: 'my-app',
  template: '<input type="text" [(ng-model)]="title" /><h1>{{title}}</h1>',
  directives: [ CORE_DIRECTIVES ]
})
class AppComponent {
  title :string;

  constructor() {
    this.title = 'hello angular 2';
  }
}
bootstrap(AppComponent);

我是Angular的新手，但对我来说，只需导入Input就能找到解决方案。这不是我的功劳，在另一块黑板上找到的。如果你有同样的问题，这是一个简单的解决方法，但如果你的问题更复杂，我会阅读上面的东西。

穆克什:

你必须像这样在子组件的顶部导入输入

import { Directive, Component, OnInit, Input } from '@angular/core';

其他回答

@VahidN，我找到我需要的了

    "exclude": [
        "node_modules",
        "typings/main",
        "typings/main.d.ts"
    ]

在我的tsconfig中，也可以停止es6-shim本身的错误

对于Angular 2.0.0-rc。0添加node_modules/angular2/ types /browser.d。这行不通。首先添加类型。Json文件到您的解决方案，内容如下:

{
    "ambientDependencies": {
        "es6-shim": "github:DefinitelyTyped/DefinitelyTyped/es6-shim/es6-shim.d.ts#7de6c3dd94feaeb21f20054b9f30d5dabc5efabd"
    }
}

然后更新包。Json文件，包括这个postinstall:

"scripts": {
    "postinstall": "typings install"
},

现在运行npm install

另外，现在您应该忽略tsconfig中的typings文件夹。Json文件以及:

 "exclude": [
        "node_modules",
        "typings/main",
        "typings/main.d.ts"
    ]

更新

现在AngularJS 2.0使用core-js代替es6-shim。遵循它的快速开始打字。Json文件获取更多信息。

我可以通过安装typings模块来解决这个问题。

npm install -g typings
typings install

(使用ng 2.0.0-rc.1)

2016-05-13 22:46:55

如果npm install -g typings typings install仍然不起作用，请在执行该命令之前删除node_modules和typings文件夹。

2016-07-29 12:09:58

您可以在.ts文件的开头添加代码。

/// <reference path="../typings/index.d.ts" />
