Rails is Nuked - 再インストール方法

Question

Nuked Railsのインストールを再インストールするのに約3時間を費やしました。 「authlogic」の宝石をインストールしようとした後に動作を停止しました（誰かがそれをインストールする方法を知っていれば、私に教えてください）。

NEW ERROR

OLD PROBLEM

の手順は次のようなものだった： "sudoの宝石がauthlogicをインストールし、" 入力した後 1.ハァハァRailsの 2.〜/を削除してみてください.rvmはまだ動作しません 3. gemアンインストールを使用して、gemリストに何も表示されなくなるまで、すべてのgemを削除します。--local 4. sudo gem install rails

"rails"は動作しますが、Railsプロジェクトの外部でのみ動作します。私がレールアプリに入り、レールサーバーを走らせると、次のようになる：

Could not find rake-0.9.2.2 in any of the sources 

明らかにレーキはなくなった。しかし、Railsプロジェクトの中でのみ（新しいものでさえ）！レールとレーキの両方が動作しますが、Railsプロジェクトディレクトリにcdすれば両方とも失敗します。

私はMac OS 10.7.3を使用しています。sudo gem install authlogicを使用するまで、すべてがうまく機能しました。

Answer 1

ここの難しさは、これらの宝石がすべて消えたことをバンドラーが認識していない可能性が高いです。あなたのRailsディレクトリに行き、 'bundle install'を実行してみてください。これはあなたのすべての宝石が帰ってくるはずです。
