尝试在OSX El Capitan升级后安装thift gem：
$gem install thrift
Building native extensions. This could take a while...

解决方法
我有一个解决方案给你！希望.
有一天有同样的问题.
问题在于El Capitan捆绑的clang编译器.我确定它拧紧了其他问题,但这是一个问题,我有很多问题.
尝试运行以下命令,让我知道它是怎么回事！
gem install thrift -- --with-cppflags=\"-D_FORTIFY_SOURCE=0 -Wno-shift-negative-value\"
