Can'；t通过RVM在Mac 10.8上安装ruby 1.8.7

我无法在Mac 10.8.2上安装ruby ree或ruby 1.8.7

我做到了：

$ brew install libksba
$ brew update
$ brew install autoconf automake
$ brew tap homebrew/dupes
$ brew install autoconf automake apple-gcc42

然后我尝试安装ruby 1.8.7，但我不能

$ rvm install 1.8.7

make.Log中的日志是

看起来rvm没有找到随brew安装的

apple-gcc42

确保

gcc-4.2

可通过

PATH

访问，或使用指向它的路径运行安装：

rvm reinstall 1.8.7 --with-gcc=/path/to/brew/apple-gcc42/gcc-4.2

---

编辑1：

刚刚选中，RVM还搜索

gcc-apple-4.2

，因此如果它位于

路径上，RVM将自动使用它-这已在RVM 1.16.8中更新。
好的，我找到了解决方案

删除Xcode
我从网上下载了山狮的软件包
安装下载的osx gcc安装程序
安装Xcode（和命令行工具）
仅此而已。
我尝试了GCC软件包，安装/卸载了Xcode等，但我认为有效的方法是：

rvm get stable

（响应包括另一个命令：

sudo sed -i'' -e "s#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib CFLAGS=-I/opt/sm/pkg/active/include CPATH=/opt/sm/pkg/active/include')#rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')#" /etc/rvmrc

)

我很确定这是成功的原因：

rvm install 1.9.3

对于任何需要Xcode的人来说，这是一个不可接受的解决方案。请看上面使用自制软件安装apple-gcc42的@mpapis解决方案（显然，gcc42是从Xcode 4.2开始删除的）。在那之后，rvm安装1.8.7没有问题。这确实帮助了我。做
rvm得到稳定
，然后它就开始工作了。
