我在安装Ruby 1.9.3时遇到问题，我不知道是否重要，但我使用ML POST FACTOR在我的旧Mac上运行os x 10.8
以下是错误

看起来你要么没有C编译器，要么你正在使用的C编译器不理解RVM使用的一些标志。
此外，您引用的日志是错误的。该错误已记录在/Users/Tyler/.rvm/log/1408657159_ruby-1.9.3-p547/configure.log。
有些用户在评论中建议安装Xcode 您需要安装Xcode才能在Mac上进行软件开发（因为它还安装了其他CLI实用程序），但您不应使用默认的Xcode编译器来构建Ruby MRI 1.9.3。
Xcode编译器是clang（llvm），但Ruby MRI 1.9仅支持gcc（另一种较旧但广泛使用的编译器）。
虽然MRI 1.9.3 非正式地与clang兼容，但是存在一些已知问题，并且某些模块无法正确编译（光纤）。
MRI 2.0.0已添加完整clang支持。
因此，如果您确实要安装MRI 1.9.3，则需要先安装gcc：
brew update
brew install gcc-4.9
rvm install 1.9.3 --with-gcc=/usr/local/bin/gcc-4.9
