Node.js インストール
nodejs ダウンロード
自分はCドライブ直下に"Development"フォルダを作って以下にインストール。バージョンはv4.4.4
C:\Development\nodejs\v4.4.4
##環境変数の設定
-
[スタート]を右クリック
-
[システム] > [システムの詳細設定] > [詳細設定]タブから[環境変数]をクリック
-
NODE_HOME変数作成
- ○○のユーザ環境変数で[新規]をクリック
- 変数名「NODE_HOME」/ 変数値「C:\Program Files\nodejs\v4.4.4」設定。
-
PATH変数修正
- PATHを選択して[編集]をクリック
- 変数値に「;%NODE_HOME%」を追記。先程の例だと以下
C:\Development\nodejs\v4.4.4;%NODE_HOME%
##Electronのインストール
先ほどのnode.exeのあるディレクトリで
> npm -g install electron-prebuilt
※自分はこのあたりでPCを再起動した。
##ElectronのHello World
公式のQuick Startを見ながら３つのファイルを用意。全部コピペ。
