构建：重复标识符“原型”

Question

当我尝试构建我的应用时，出现以下错误：

1>node_modules\angular2\typings\browser.d.ts(6,14): error TS2300: Build: Duplicate identifier 'PromiseConstructor'.
1>node_modules\angular2\typings\es6-collections\es6-collections.d.ts(22,5): error TS2300: Build: Duplicate identifier 'done'.
1>node_modules\angular2\typings\es6-collections\es6-collections.d.ts(23,5): error TS2300: Build: Duplicate identifier 'value'.

1>node_modules\angular2\typings\es6-promise\es6-promise.d.ts(42,16): error TS2300: Build: Duplicate identifier 'Promise'.

我不明白为什么。这是我的 tsconfig：

{
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "module": "commonjs",
    "noEmitOnError": true,
    "noImplicitAny": false,
    "outDir": "../wwwroot/appScripts/",
    "removeComments": false,
    "sourceMap": true,
    "target": "es5"
  },
  "exclude": [
    "node_modules"
  ]
}

我不知道为什么会出现此错误。我已按照本教程进行操作：http://www.mithunvp.com/angular-2-in-asp-net-5-typescript-visual-studio-2015/

检查您的 es6-collections.d.ts 是否被多次导入。多次引用时会出现此类问题。
