我使用通过 RVM 安装的 ruby 2.0.0 在我的工作站上运行 Ubuntu 13.04。

我使用命令安装了 nokogiri，因为它使用的是 libxml2 版本 2.8.0，但我不确定它从哪里获取，因为只有 libxml2 是通过 apt 安装的。
gem install nokogiri -- --with-xml2-include=/usr/include/libxml2/libxml --with-xslt-dir=/usr/include/libxslt
当我运行我的应用程序时，我收到以下错误：
/home/pb/.rvm/rubies/ruby-2.0.0-p195/lib/ruby/site_ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in require': /home/pb/.rvm/gems/ruby-2.0.0-p195/gems/nokogiri-1.6.0/ports/x86_64-linux-gnu/libxml2/2.8.0/lib/libxml2.so.2: versionLIBXML2_2.9.0' not found (required by /home/pb/.rvm/gems/ruby-2.0.0-p195/gems/libxml-ruby-2.6.0/lib/libxml_ruby.so) - /home/pb/.rvm/gems/ruby-2.0.0-p195/gems/libxml-ruby-2.6.0/lib/libxml_ruby.so (LoadError)
谁能告诉我如何摆脱 libxml2 2.8.0 版？
谢谢
