急にrailsコマンドが使えなくなった

急にrailsコマンドが使えなくなりました

rails -vとrails newだけはできるのですが、既存のファイルは

Usage:
  rails new APP_PATH [options]

以下省略

と出て、rails newで新しく作ったファイルは、

/Users/.rbenv/versions/2.4.1/lib/ruby/gems/2.4.0/gems/activesupport-3.0.5/lib/active_support/values/time_zone.rb:272: warning: circular argument reference - now

と出ます。

カレントディレクトリの間違いはないです。
複数ファイルで検証して全部同じ結果だったので、ファイルの問題はないかと思われます

rubyのバージョンは2.4.1
railsのバージョンは3.0.5

OSはMacです。

宜しくお願い致します。
