Jekyllのビルドに失敗しました：Liquid Exception：そのようなファイルをロードできません--yajl

つい最近、PCを汚し、しばらくの間Jekyll、または実際にはRubyを使用していませんでしたが、すべてを正しくセットアップしたと思った後、実行しようとすると...

jekyllビルドまたはjekyllサーブ

このエラーが発生します：

どういうわけかpygments.rbに関係していると思います。シンタックスハイライトのデモがある最初の投稿を削除すると、ビルドは機能します。pgymentsを0.5.4に更新しようとしましたが、これは何の違いもないようです。pygments.rbが0.3.4にロックされているというエラーが発生したと思います。

You have requested:
  pygments.rb ~> 0.5.4

The bundle currently has pygments.rb locked at 0.3.7.
Try running `bundle update pygments.rb`

誰かがこれに光を当てることができますか？それは私を狂わせています。Ruby2.0.0p353を実行しています。
