我做错了什么？

@mu太短了，这是正确的

使用brew安装gtk+

@mu太短，请立即安装

使用brew安装gtk+

是否安装了gtk？正在检查gobject-2.0。。。否表示您没有glib，这是GTK需要的。我已经从git clone下载了GTK+git://git.gnome.org/gtk+我仍然收到同样的错误你编译并安装了吗？这可能是您进行此类操作的最佳选择，一旦安装完毕，您就可以brew安装gtk+，这应该会解决问题。您是否安装了gtk？正在检查gobject-2.0。。。否表示您没有glib，这是GTK需要的。我已经从git clone下载了GTK+git://git.gnome.org/gtk+我仍然收到同样的错误你编译并安装了吗？这可能是您在这类事情上的最佳选择，一旦有了它，您就可以brew安装gtk+，这应该会解决问题。
