在 Mountain Lion 上安装 Ruby 时出现问题 - ruby​​ 1.9.3 无法编译

Question

我之前看过很多关于此的帖子，并按照他们的指示进行操作，但没有任何效果。我将在下面概述我所做的事情，以及我遵循的说明 - 如有任何建议，我将不胜感激！

我已按照以下安装说明进行操作： http://pragmaticstudio.com/blog/2010/9/23/install-rails-ruby-mac

我已经下载了 OSX Mountain Lion 的 X-code，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)
Copyright (C) 2007 Free Software Foundation, Inc.
This is free software; see the source for copying conditions.  There is NO
warranty; not even for MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

然后我按照指示完成并安装了最新版本的git

$ git --version
git version 1.7.10.2 (Apple Git-33)

同样通过命令行对 rvm 进行同样的操作：

$ rvm --version
rvm 1.16.13 (stable) by Wayne E. Seguin <wayneeseguin@gmail.com>, Michal Papis <mpapis@gmail.com> [https://rvm.io/]

当我尝试使用 RVM 安装 ruby​​ 时，我得到以下信息：

$ 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.

使用备用命令行虽然有一些额外的位，但我得到了类似的输出：

$ 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，我得到以下信息：

$ less /Users/mondemoo/.rvm/log/ruby-1.9.3-p286/configure.log

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

我现在对自己做错了什么感到非常困惑-有人可以提供帮助吗？ c编译器（gcc？）似乎存在问题，我是否正确解释它？如果是这样，我该如何解决？另外，如何访问上面 configure.log 中提到的“config.log”？

谢谢！

这是 RailsInstaller OSX 1.0.3 中的一个错误 - https://github.com/railsinstaller/railsinstaller-nix/issues/10

您需要更改 /etc/rvmrc 以包含此内容：

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')

当二进制 ruby​​ 可用于 2.0.0 时，我将准备新版本的安装程序。

更新：对于新版本的 RVM 1.19+ /etc/rvmrc 应更改为：

umask g+w
export rvm_autolibs_flag=smf

然后运行rvm get stabel #OR: head

不确定我是否以“正确”的方式进行操作，但我只是删除了 RVM (rvm implode)，然后重新安装了它 (\curl -L https://get.rvm.io | bash -s stable --ruby) 并且它已安装并且现在运行最新版的ruby 1.9.3-p327没问题。
