Corporatura: Duplicate identificatore 'prototipo'

Question

Quando si cerca di costruire la mia app, ho ottenuto i seguenti errori:

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-collections\es6-collections.d.ts(46,5): error TS2300: Build: Duplicate identifier 'size'.

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

non capisco perché. Qui è la mia TSconfig:

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

non ho idea perché ottengo questo errore. Ho seguito questo tutorial: http://www.mithunvp.com/angular-2-in-asp-net-5-typescript-visual-studio-2015/

Controlla che es6-collections.d.ts venga importato più di una volta. Questo tipo di problema si verifica quando il riferimento viene eseguito più di una volta.
