Question

にbcryptのを「NPMインストール」する方法今、私が使用していた私は、NPMバージョン4.1.2と一緒のNode.jsのv6.9.1をインストールしていると私はすでに

いくつかのプロジェクトのために、この組み合わせを使用しましたbcrypt NPMの私のプロジェクトでパッケージが、インストールは無残

npm install bcrypt --save 

私も、これは私が

取得エラーで無駄

に、管理者priviledgesでこのコマンドを実行しようとしたが失敗しました

npmはあらかじめ構築されたバイナリを見つけることができないので、pythonを使ってソースをコンパイルしようとしています（私は持っていないようです）。

このためにPythonをインストールする必要はありますか？はいの場合、正しい方向に私を向けることができますか？ bcryptの事前構築版がないのは事実ですか？

EDIT：Python 2.7をインストールした後で、MSBuildを使ってC++コードをコンパイルしようとしたようです。

Answer 1

あなたはこれを試すことができます。

最初のグローバルノードGYPをインストールします。

npm install node-gyp -g 

その後、私の答えは否決された理由私はわからない

npm install bcrypt --save 

を実行します。..私は、エラーメッセージから解決策を推測していました。

次の今回試すことができます：Visual Studioの2012/13エクスプレス（またはその他）をインストール

は、インストールのPython http://www.python.org/download/releases/2.7.5/ を （Windowsの7月8日）は、Windows SDKをインストールし のWin64のOpenSSL v1.0.1gをインストールします。管理者とテストがインストールとして

開く "VS2012のための開発者コマンドプロンプト"：

その後

NPM INSTAL -g NPMインストールリットルノード-GYP bcryptの-gあなたは私に言わせれば、私はそれが
