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);

当前回答

当Typescript >= 2时，tsconfig中的"lib"选项。Json就可以了。不需要Typings。https://www.typescriptlang.org/docs/handbook/compiler-options.html

{
    "compilerOptions": {
        "target": "es5",
        "lib": ["es2016", "dom"] //or es6 instead of es2016(es7)
    }
}

其他回答

对于那些学习Angular2教程的人来说。为了明确起见，这里是mvdluit关于在哪里放置代码的答案的扩展:

你的主。t应该是这样的:

/// <reference path="../node_modules/angular2/typings/browser.d.ts" />

import {bootstrap} from 'angular2/platform/browser'
import {AppComponent} from './app.component'
// Add all operators to Observable
import 'rxjs/Rx'

bootstrap(AppComponent);

注意，您在///前斜杠中保留，不要删除它们。

@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

更新tsconfig。json,改变

"target": "es5"

to

"target": "es6"

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)
