Manjaro GNOME 18.0_x86-64にcreate-elm-appでElmプロジェクトを作成

環境が動かない場合は、だいたい公式ドキュメントの情報をスルー

して、自己流で「多分こうなるはず」で動かしてる場合が多い。

create-elm-appも「-g」オプションがあるからグローバルにインストール

を敬遠で無理やり試行錯誤じゃなくて、とりあえず、公式ドキュメント

に従って作業してみるべきだと思った(深く反省)

[手順]

1. npm or yarn でグローバルにインストール。

% npm install -g create-elm-app または

% yarn global add create-elm-app
