我以前曾在此上看到过许多帖子，并且遵循了他们的说明，但没有任何作用。我将在下面概述我所做的工作以及所遵循的说明 - 对任何建议都表示感谢！
我遵循以下安装说明：http://pragmaticstudio.com/blog/2010/9/23/install-rails-rails-ruby-mac
我已经为OSX Mountain Lion下载了X代码，并安装了GCC编译器：
$ gcc --version
i686-apple-darwin11-llvm-gcc-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

$ git --version
git version 1.7.10.2 (Apple Git-33)
类似地通过命令行与RVM进行了同样的操作：
$ rvm --version
rvm 1.16.13 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]
然后，当我尝试使用RVM安装Ruby时，我会得到以下内容：
$ rvm install 1.9.3
No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p286.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.

There has been an error while running configure. Halting the installation.
使用替代命令行，我得到了类似的输出，尽管有一些额外的位：
$ rvm install 1.9.3 --with-gcc=clang
-bash: -dumpversion: command not found
-bash: --version: command not found
-bash: --version: command not found

There has been an error while running configure. Halting the installation.
-bash: --version: command not found
查看configure.logs，我得到以下内容：
$ less /Users/mondemoo/.rvm/log/ruby-1.9.3-p286/configure.log

configure: error: in `/Users/mondemoo/.rvm/src/ruby-1.9.3-p286':

我现在对我做错了什么完全感到困惑 - 有人可以提供帮助吗？看来C兼委员会（GCC？）有一个问题，我在正确解释吗？如果是这样，我该如何解决？另外，我如何获得上面configure.log中提到的" config.log"？
谢谢！
这是Railsinstaller OSX 1.0.3- https：//github.com/railsinstaller/railsinstaller-nix/sissues/10
您需要更改/etc/rvmrc才能包含以下内容：
umask g+w
export -a rvm_configure_env
rvm_configure_env=('LDFLAGS=-L/opt/sm/pkg/active/lib' 'CFLAGS=-I/opt/sm/pkg/active/include' 'CPATH=/opt/sm/pkg/active/include')
我将准备新版本的安装程序，当二进制Ruby可用于2.0.0。
更新：对于新版本，RVM 1.19+ /etc/rvmrc应该更改为：
umask g+w
export rvm_autolibs_flag=smf
并运行rvm get stabel #OR: head
不确定我以'正确'的方式做到了，但是我只是删除了rvm（rvm爆炸），然后重新安装它（ curl -l -l -l https：//get.rvm.io |bash -s稳定-ruby）并已安装，现在正在运行最新版本的Ruby 1.9.3 -P327没问题。
