Railsが適切なバージョンのRubyを認識できないようにしているシンボリックリンクをいくつか設定したことが関係しているのではないかと思います。バージョン1.8に戻り続けています。通常、RVM を使用すると異なるバージョンの Ruby 間を移動するのは簡単でしたが、それ以上はできなくなりました。どう思いますか？

rvm で sudo を使用する必要はありません。rvm の使用方法については、 rvm サイトにアクセスしてください。問題が発生した場合は、irc freenode サーバーの #rvm で私 (mpapis) に参加してください。

Ruby のインストールが壊れているように見えます/usr/local/rvm/rubies/ruby-1.9.3-p194/bin/gem。

rvm get head 
rvm reload
rvm reinstall 1.9.3
