问题描述

Mac用户，请参阅: Mac用户并得到警告:Nokogiri是针对LibXML 2.7.8版构建的，但已动态加载2.7.3

Mac users, see: Mac user and getting WARNING: Nokogiri was built against LibXML version 2.7.8, but has dynamically loaded 2.7.3

我正在使用linux(openSUSE 12.3)并运行nokogiri -v显示:

I'm using linux (openSUSE 12.3) and running nokogiri -v shows:

推荐答案

此处的隐式问题似乎是为什么收到此警告，对此我该怎么办?"

The implicit question here seems to be "why am I getting this warning, and what can I do about it?"

您会收到警告，因为Nokogiri是针对LibXML 2.8.0版构建的(它是一个本机扩展的gem，需要编译)，并且您的系统此后已将LibXML升级到2.9.0版.

You are getting the warning because Nokogiri was built (it is a largely native-extension gem, requiring compilation) against LibXML version 2.8.0, and your system has since upgraded LibXML to version 2.9.0.

这是一个警告，并非有错误-在许多情况下，Nokogiri可以继续使用比其所针对的新版本LibXML更好的工作.

This is a warning, not at error -- in many cases, Nokogiri will continue to work fine with a newer version of LibXML than it was built against.

如果您遇到问题或只是为了安全起见，重建Nokogiri将解决此问题-将根据当前安装的LibXML版本进行构建.

If you run into problems or just want to be on the safe side, rebuilding Nokogiri will solve the issue -- it will be built against the version of LibXML currently installed.
