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

Angular 2 RC1将node_modules/angular2目录重命名为node_modules/ Angular。

如果你使用gulpfile将文件复制到输出目录,你可能仍然有node_modules/angular在那里,它可能会被编译器拾取,并将自己弄得一团糟。

因此(小心地)清除node_modules中用于beta版本的内容,并删除任何旧的类型并重新运行类型install。

其他回答

 typings install dt~es6-shim --save --global

并将正确的路径添加到index.d.ts

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

在@angular-2.0.0-rc3上尝试

@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

在应用程序的主文件夹中添加typing.d.ts,并在那里声明你每次都要使用的变量

declare var System: any;
declare var require: any;

在typing.d中声明之后。Ts,在应用程序中不会出现require的错误。

我也遇到了同样的问题,我使用tsconfig.json中的lib选项解决了它。正如basarat在他的回答中所说,a。d。ts文件被TypeScript隐式包含,这取决于编译目标,但这种行为可以通过lib选项改变。

你可以在不改变目标JS版本的情况下指定要包含的其他定义文件。例如,这是我当前编译选项Typescript@2.1的一部分,它添加了对es2015特性的支持,而不安装任何其他东西:

"compilerOptions": {
    "experimentalDecorators": true,
    "lib": ["es5", "dom", "es6", "dom.iterable", "scripthost"],
    "module": "commonjs",
    "moduleResolution": "node",
    "noLib": false,
    "target": "es5",
    "types": ["node"]
}

要获得可用选项的完整列表,请查看官方文档。

还要注意,我在代码中添加了"types": ["node"],并安装了npm install @types/node来支持require('some-module')。

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)
