Compilation 警告：Nokogiri是根据LibXML版本2.7.7构建的，但动态加载了2.6.16

我不明白为什么我在启动Rails时从Nokogiri那里得到这个错误。据我所知，似乎是其他原因导致加载了旧版本的libxml2，Nokogiri最终使用了旧版本，而不是它编译时所使用的版本

在没有警告的情况下（并且使用正确的libxml2），我需要做什么才能让它正常工作

我正在使用OS X 10.5.8的Macbook上运行此功能：

$rake数据库：创建

你好您使用的是libxml2版本2.6.16，该版本已有4年历史，并且
很多虫子。我们建议，为了获得最大的HTML/XML解析乐趣，您可以
升级您的libxml2版本并重新安装nokogiri。如果你喜欢使用
libxml2版本2.6.16，但不喜欢此警告，请定义常量
在要求nokogiri之前，我知道我正在使用旧版和小车版的LIBXML2。
