我正在使用 Angular（版本 2）和 TypeScript（版本 1.6），当我编译代码时出现以下错误：

@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);

2.0.0-beta.6 (2016-02-11) 的变更日志中提到了一种解决方法（列在重大变更下）：
If you use --target=es5, you will need to add a line somewhere in your application (for example, at the top of the .ts file where you call bootstrap):
///<reference path="node_modules/angular2/typings/browser.d.ts"/>
(Note that if your file is not in the same directory as node_modules, you'll need to add one or more ../ to the start of that path.)
请确保您有正确的引用路径，我需要在开头添加 ../ 才能使其正常工作。

当以 ES5 为目标时，ES6 功能（如承诺）未定义。还有其他库，但 core-js 是 Angular 团队使用的 javascript 库。它包含 ES6 的 polyfill。
自从提出这个问题以来，Angular 2 发生了很大变化。在 Typescript 2.0 中，类型声明 更容易 使用。
npm install -g typescript
对于 Angular 2 中的 ES6 功能，您不需要 Typings。只需使用 typescript 2.0 或更高版本并使用 npm 安装 @types/core-js：
npm install --save-dev @types/core-js
然后，将 TypeRoots 和 Types 属性添加到您的 tsconfig.json：
{
"compilerOptions": {
"target": "es5",
"module": "es6",
"moduleResolution": "node",
"sourceMap": true,
"emitDecoratorMetadata": true,
"experimentalDecorators": true,
"removeComments": false,
"noImplicitAny": false,
"typeRoots": [
"../node_modules/@types"
],
"types" : [
"core-js"
]
},
"exclude": [
"node_modules"
]
}
这比使用 Typings 要容易得多，如其他答案中所述。有关详细信息，请参阅 Microsoft 的博客文章： Typescript：声明文件的未来

已知问题： https://github.com/angular/angular/issues/4902
核心原因：TypeScript 隐式包含的
.d.ts
文件随编译目标而变化，因此在定位
es5
时需要有更多环境声明，即使运行时（例如 chrome）中确实存在某些内容。有关
lib.d.ts
