Windows マシンで twitter-bootstrap-rails gem を動作させる作業を行っていましたが、less gem の古いバージョンに依存する 'therubyracer' gem をインストールしようとしてエラーが発生しました。
therubyracer に依存しない 2.2.1 未満にアップグレードしたと思いますが、それでもまだ therubyracer をインストールする必要があると思われるようです。Railsサーバー「rails s」を起動しようとしたときに表示されるエラーの出力は次のとおりです。
$ rails s
[WARNING] Please install gem 'therubyracer' to use Less.

これが私GemfileのGemfile.lockファイルです。「therubyracer」をインストールする必要がないことをアプリに伝える方法を誰かが教えてくれますか?
