ActiveRecord oracle_enhancedアダプターはruby-oci8ライブラリーをロードできませんでした

Question

rails g scaffoldが失敗しましたが、ociスクリプトとirbデータ照会が機能しました。何が間違っているのか分からなかった。

rails g scaffold table field1:integer field2:string ....

IRBを経由して行く：

私はルビー鉱山から実行されている同様の問題があった：

あなたはに設定されたOracle clinetパス持っていますか：私は私の端末でそれらを設定していた

DYLD_LIBRARY_PATH 

を、 RubyMineが実行中のプロファイルで環境変数を設定していることを確認しなければなりませんでした。

DYLD_LIBRARY_PATH=/usr/local/oracle/instantclient10_2 
NLS_LANG=AMERICAN_AMERICA.UTF8 

スクリプトを実行すると、端末と同じ場所で環境変数が検索されないことがあります。私はGoogleで検索して、この見つかっ

興味深い

env DYLD_LIBRARY_PATH=$DYLD_LIBRARY_PATH NLS_LANG=$NLS_LANG rails g scaffold ...
