虽然bundle：部署后安装阶段：finalize_update,我收到有关nokogiri的错误.它表明,
** [out :: *******] Make sure that `gem install nokogiri -v '1.6.0'` succeeds before bundling.
所以我试图在服务器上自己安装nokogiri.但它给出以下错误,
Building native extensions. This could take a while...

它今天刚刚开始.还有libxml2已经安装.
任何想法？
谢谢.
编辑：我不需要明确的nokogiri在我的宝石文件.
解决方法
我在Nokogiri 1.6.0中遇到了同样的问题.从日志中可以看出,问题是由于libxml2的编译失败而导致的,它与libxslt一起现在已经嵌入到gem中并在安装时被编译.
要弄清楚编译出了什么问题,请查看建议的文件compile.log,在您的情况下,可以在以下位置找到：
/home/deployer/.rvm/gems/ruby-2.0.0-p0/gems/nokogiri-1.6.0/ext/nokogiri/tmp/x86_64-linux-gnu/ports/libxml2/2.8.0/compile.log
作为一种解决方法(假设您已经安装了libxml2-dev和libxslt-dev),您可以执行以下操作：
NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install
我希望它有帮助.
