我已经设置了 rvm 并想做教程http://zetcode.com/gui/rubygtk/

它需要gtk2所以我跑了：

gem install gtk2

它要求我授权安装 libglib2.0-dev

最后它因错误而失败。

 This is the log

编译 ruby​​ 时，这些错误看起来像是clangOSX 上的问题，但它可能只是与 不兼容ruby-2.0.0-p0，请确保您拥有gcc不是LLVM基于的：

gcc -v | grep -i llvm

输出应该是空的，然后得到旧的红宝石：

rvm use 1.9.3 --install --default

并再次安装 gem：

gem install gtk2

如果可行，则为 gem 打开一个错误，以提高与任一clang和/或的兼容性ruby-2.0.0
