我一直在努力让 twitter-bootstrap-rails gem 在我的 Windows 机器上运行，并在尝试安装“therubyracer”gem 时遇到错误，这是旧版本的 less gem 的依赖项。
我认为升级到不依赖于 therubyracer 的 less 2.2.1 但是尽管如此，它似乎认为我仍然需要安装 therubyracer。这是我尝试启动 Rails 服务器“rails s”时得到的错误输出。
$ rails s
[WARNING] Please install gem 'therubyracer' to use Less.

这是我的Gemfile和Gemfile.lock文件。谁能帮我弄清楚如何告诉我的应用它不需要安装“therubyracer”？
