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

@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

其他回答

这就是为什么每个人都在尝试做一些不同的事情。我相信这些系统离最终版本还很远。

在我的例子中，我从rc更新。0到rc。5 .出现此错误。

我的修复是改变tsconfig.json。

{
    "compilerOptions": {
        "target": "es6", <-- It was es5
        "module": "system",
        "moduleResolution": "node",
        "sourceMap": true,
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "removeComments": false,
        "noImplicitAny": false,
        "outDir": "../wwwroot/app"
    },
    "compileOnSave": true,
    "exclude": [
        "../node_modules",
        "../typings/main"
    ]
}

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。

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)
    }
}

在2.0.0-beta.6的更新日志中提到了一个解决方案(2016-02-11)(有重大变动):

如果你使用——target=es5，你需要在你的应用程序的某个地方添加一行(例如，在你调用bootstrap的.ts文件的顶部):

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

(请注意，如果您的文件与node_modules不在同一个目录中，则需要添加一个或多个../到路径的起点。)

确保你有正确的参考路径，我需要添加../开始让它工作。

一个已知的问题:https://github.com/angular/angular/issues/4902

核心原因:。d。TypeScript中隐式包含的ts文件随着编译目标的不同而不同，所以当目标为es5时，即使在运行时(例如chrome)中确实存在一些东西，也需要有更多的环境声明。更多关于lib.d.ts
