最近、「ar-extension」gemをインストールしました。インストール後、railscまたはrailssを実行すると、次のエラーが発生します。

私はエラーをグーグルで検索しましたが、無駄に..Plzはxactlyが間違っていることを知るのに役立ちます。

使用しようとしている宝石は、レール3.2と互換性がありません。class_inheritable_accessorを支持して非推奨になりましたclass_attribute。

この宝石のレール3.2フォークを探したり、独自のポートを作成したり、代替品を検索したりできます。

実際、ar-extensionsはrails3では動作しません。rails3の代わりにアクティブなインポートがあり、完全に正常に動作します。.;）

Rails3にはactiverecord-importgemを使用してください
