我正在尝试在终端中运行以下命令：
gem install bundler && bundle install --without test development
但是让我知道关于 Ruby 版本的错误，你可以在下面看到登录：

Installing nokogiri (1.6.0)
Gem::InstallError: nokogiri requires Ruby version >= 1.9.2.
An error occurred while installing nokogiri (1.6.0), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.
我的 Ruby 版本是：（ruby -v）
ruby 1.9.2dev (2010-07-02) [i486-linux]
任何想法，将不胜感激。
