に示すエラーは、私も同じディレクトリにファイルをpackage.jsonています私はこの問題を解決する方法を知っています。 ありがとう

npmを使用するためにpackage.jsonファイルがありません。すべての依存関係を持つものを作成する必要があります。あなたのルートフォルダにpackage.jsonを修正/追加すると、うまくいくはずです。

{ 
    "name": "myapp", 
    "version": "0.0.1", 
    "dependencies": {}, 
    "devDependencies":{} 
} 

更新： 私はこのプロジェクトhttps://github.com/AngularClass/angular2-webpack-starter.gitをクローニングして、インストールして起動することができましたしました。ここ

は簡単package.jsonです。現在のバージョンのプロジェクトははるかに進んでおり、魅力的に機能しています。あなたはどうやってそれを試みますか？
