Rbenv无法安装rubinius

Question

我试图通过rbenv安装rubinius，但出现了这个错误。我不知道这里出了什么问题。

下面是安装jruby的(成功)结果

如果不完整地查看日志文件，就很难确切地知道问题是什么。我能够在OSX 10.9.4上安装最新版本的ruby-build，并安装了homebrew。不过，我必须先使用brew install llvm。

我建议看看rbenv install在幕后使用的https://github.com/rbenv/ruby-build。在我使用rbenv install的经验中，问题通常是使用了错误的c编译器，或者缺少库。

一些用于检查系统默认值的有用命令如下：

which cc
which g++
cc --version
g++ --version

检查您的$PATH设置echo $PATH
