我正在使用带有TypeScript(版本1.6)的Angular(版本2),当我编译代码时,我得到以下错误:
Error TS2304: Cannot find name 'Map'.
node_modules/angular2/src/core/change_detection/parser/locals.d.ts(4,42): Error TS2304: Cannot find name 'Map'.

node_modules/angular2/src/core/facade/collection.d.ts(14,23): Error TS2304: Cannot find name 'Map'.
node_modules/angular2/src/core/facade/collection.d.ts(15,25): Error TS2304: …我刚刚从Angular 2 beta16升级到beta17,后者又需要rxjs 5.0.0-beta.6.(更改日志:https://github.com/angular/angular/blob/master/CHANGELOG.md#200-beta17-2016-04-28)在beta16中,所有关于Observable/map功能的都很好.升级后出现以下错误,当typescript尝试转换时出现:
- 类型'Observable'上不存在属性'map'(我在地图中使用了带有observable的地图)
- c:/path/node_modules/rxjs/add/operator/map.d.ts(216):error TS2435:Ambient模块不能嵌套在其他模块或名称空间中.
- c:/path/node_modules/rxjs/add/operator/map.d.ts(2,16):错误TS2436:环境模块声明无法指定相对模块名称.
我已经看到了这个问题/答案,但它没有解决问题: Angular2 beta.12和RxJs 5 beta.3的可观察错误
我的appBoot.ts看起来像这样(我已经引用了rxjs/map):
///<reference path="./../node_modules/angular2/typings/browser.d.ts"/>
import {bootstrap} from "angular2/platform/browser";
import {ROUTER_PROVIDERS} from 'angular2/router';
import {HTTP_PROVIDERS} from 'angular2/http';
[stuff]
import 'rxjs/add/operator/map';
import 'rxjs/add/operator/toPromise';
import {enableProdMode} from 'angular2/core';
import { Title } from 'angular2/platform/browser';
//enableProdMode();
bootstrap(AppDesktopComponent, [
ROUTER_PROVIDERS,
HTTP_PROVIDERS,
Title
]);
有人知道发生了什么事吗？
在将Angular Cli从SystemJs切换到Webpack之后,我不确定如何包含JS文件(供应商).
例如
选项A.
我有一些通过npm安装的js文件.像这样在head标签中添加脚本标签不起作用.它似乎也不是最好的方式.
<head>
<script src="node_modules/some_package/somejs.js">
</head>
//With systemJs I could do this
<head>
<script src="vendor/some_package/somejs.js">
</head>
选项B.
将这些js文件包含在webpack包中.这似乎应该是它应该做的方式.但是我不知道如何做到这一点,因为所有的webpack代码似乎都隐藏在angular-cli-webpack节点包之后.我想也许还有另一个我们可以访问的webpack配置.但我不确定,因为在创建一个新的angular-cli-webpack项目时我没有看到.
更多信息:
我想要包含的js文件需要包含在Angular项目之前.例如jQuery和第三方js lib,它实际上没有为模块加载或打字稿设置.

大家好,我在stackoverflow上经历了所有解决方案.但对我来说没有任何工作.因此发布问题. tsconfig.json

Error:(52, 14) TS1219:Experimental support for decorators
is a feature that is subject to change in a future release.
Set the 'experimentalDecorators' option to remove this warning.
但在我的tsConfig experimentalDecorators中设置为true:
{
"version": "1.5.0",
"compilerOptions": {
//...,
"experimentalDecorators": true, // <======== HERE
//...,
},
"files": [

}
首先:我检查过这些:
https://github.com/angular/angular/issues/7052
https://github.com/angular/angular/issues/4902
尽管使用ECMAScript 6,却打字稿找不到名字'Promise'
如何摆脱Angular2/TypeScript错误无法找到地图,承诺...当定位-es5时
还有很多很多.现在已经敲了两天头.
是的:
我在我的boot.ts文件(或引导程序文件)中引用了:
///<reference path="../node_modules/angular2/typings/browser.d.ts"/>
现在,问题是:我正在使用Visual Studio 2015 W/Update 1和ASP.NET MVC 6项目(Release Candidate 1)+ Typescript 1.8.1.
我使用本教程进行设置:http: //www.mithunvp.com/angular-2-in-asp-net-5-typescript-visual-studio-2015/
我已经成功使用Angular 2了一段时间,现在相同的代码(afaik)将无法编译.它将在browser.dmles/angular2/platform中找到"在browser.d.ts文件中找不到名称:Promise""
