我正在尝试使用Carrierwave gem将图片添加到我的网站。一旦我使用gem uploader，我得到以下错误告诉我，我有一个不兼容的库版本引用Nokogiri 1.8.1 ......

我在网上看到的大多数解决方案都包含对libxml2的引用，但我发现错误中没有引用。然而，我尝试了解决方案here但没有成功。
我已经使用brew多次卸载并重新安装了nokogiri和libxml。我还在他们的页面here上提到了在Mac上使用Nokogiri的安装。
我不是百分之百确定它是否只是一个Nokogiri错误，或者libxml2是否需要与默认版本不同的版本。我用于libxml2的当前版本是2.9.3。任何帮助或指向正确的方向将不胜感激。如果需要更多细节，请告诉我。

如果您还没有安装开发文件，请尝试安装：
sudo apt-get install g++ build-essential -y
编辑：哎呀，对于Mac，请尝试：https://github.com/kennethreitz/osx-gcc-installer
编辑：另一个想法，从Gemfile中删除Nokogiri版本然后尝试
gem install nokogiri -v 1.6.8.1 -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2
