Ruby 1.9.3不会安装吗？

我在安装Ruby 1.9.3时遇到问题，我不知道这是否重要，但我使用ML POST FACTOR在我的旧mac上运行os x 10.8

这是我得到的错误

看起来您要么没有C编译器，要么正在使用的C编译器不理解RVM使用的某些标志

另外，你引用的日志是错误的。错误已记录在

/Users/Tyler/.rvm/log/1408657159_ruby-1.9.3-p547/configure.log

中

关于编译器。 一些用户在评论中建议安装Xcode。
在mac上进行软件开发确实需要安装Xcode（因为它还安装了其他CLI实用程序），但不应该使用默认的Xcode编译器来构建Ruby MRI 1.9.3

Xcode编译器是

clang

（

llvm

），但Ruby MRI 1.9只支持

gcc

（另一个较旧但广泛使用的编译器）。
虽然MRI 1.9.3确实与

clang

非官方兼容，但仍存在一些已知问题，一些模块无法正确编译（Fibers）

MRI 2.0.0添加了完整的

clang

支持

因此，如果您真的想安装MRI 1.9.3，您需要首先安装

gcc

：

brew update
brew install gcc-4.9

rvm install 1.9.3 --with-gcc=/usr/local/bin/gcc-4.9

上面写着“查看config.log了解更多详细信息”，那么您是否查看了config.log？如果您已经安装了xcode 6，但您不了解它，那么在这里发布它将有助于我们帮助您。好的，谢谢，我将发布您是否已使用命令行工具安装了最新的xcode？我无法安装xcode 6，因为我没有os x 10.9.x-10.10.xYou正在运行预发布的测试版操作系统。对不起，你还指望什么？
