Angular2 Typescript文件的重复标识符 [英] Duplicate Identifier for Angular2 Typescript files

问题描述

在Angular2 TS快速入门之后，我最终在项目中的许多文件夹中都有重复的文件.

Following the Angular2 TS Quickstart, I end up having duplicate files in many folders across my project.

对于浏览器:

typings/browser 
node_modules/angular2/typings/browser

对于es6-shim:

For es6-shim:

node_modules/angular2/typings/es6-shim
typings/browser/ambient/es6-shim
typings/main/ambient/es6-shim

这会导致在构建过程中出现重复标识符错误.

It results in Duplicate Identifier errors during build.

我们如何防止/抑制TS引发重复的标识符错误?

How do we prevent / suppress TS from raising duplicate identifier errors?

我已将node_modules包含在我的排除列表中，但是，由于我在包含中使用了Angular2，因此由于moduleResolution节点"，TSD会将它们包含回去.替换为另一个moduleResolution值(例如经典")会导致其他问题.

这是我的tsconfig.json:

This is my tsconfig.json:

{
  "compilerOptions": {
    "target": "es5",
    "module": "system",
    "moduleResolution": "node",
    "sourceMap": true,
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "removeComments": false,
    "noImplicitAny": false,
    "outDir": "./dist"
  },
  "exclude": [
    "bower_components",
    "node_modules",
    "typings/main",
    "typings/main.d.ts"
  ]
}

更新1

这是我的appcomponent.ts:

Here's my appcomponent.ts:

///<reference path="../../node_modules/angular2/typings/browser.d.ts"/> 
import {bootstrap} from 'angular2/platform/browser';
import {LocationComponent} from '../location/components/locationcomponent';
import {VideosComponent} from '../videos/components/videoscomponent';

bootstrap(LocationComponent, [])
  .catch(err => console.error(err));

bootstrap(VideosComponent, [])
  .catch(err => console.error(err));

这是我的Web项目文件所拥有的.

This is what I have for my web project file.

更新3

我发现在Visual Studio 2015中设置Angular2需要另一种方法.我按照在ASP.NET 5中启动Angular 2中的步骤进行操作.使用Visual Studio 2015使用TypeScript ，我再也没有遇到任何构建问题.

I found out that setting up Angular2 in Visual Studio 2015 requires another approach. I followed the steps in Starting Angular 2 in ASP.NET 5 with TypeScript using Visual Studio 2015 and I didn't get any build issues anymore.
