【问题描述】：
所以我尝试在运行 Mountain Lion 的 Mac 上安装 Ruby 1.9.3。我安装了 xCode 并且是最新的。我已经安装了 RVM，现在正在尝试使用 rvm install 1.9.3 安装 Ruby 当我运行它时，它看起来像是要安装但给我一个错误，请参见下文：
rvm install 1.9.3
Searching for binary rubies, this might take some time.
No binary rubies available for: osx/10.8/x86_64/ruby-1.9.3-p392.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
Installing requirements for osx, might require sudo password.

当我转到 /1366429269_configure.log 文件时，它会说：

如果有人可以帮助我，将不胜感激！
编辑：
我在这里尝试了Can't install Ruby under Lion with RVM – GCC issuesrvm install 1.9.3 --with-gcc=clang 的解决方案，它改变了一点，这是新的输出：
rvm install 1.9.3 --with-gcc=clang
Installing requirements for osx, might require sudo password.
Already up-to-date.
Certificates in '/Users/Colin/.rvm/etc/openssl/cert.pem' already are up to date.
Warning: found user selected compiler 'clang', this will suppress RVM auto detection mechanisms.

不知道发生了什么，但我只是尝试了同样的事情，现在它运行完美。感谢所有留下有用评论的人，非常感谢！

先尝试做：
rvm get head然后再尝试安装。 -
顺便说一句，标题错误，您尝试安装的是
Ruby 1.9.3，而不是Rails -
还可以在这里查看一些解决方案：stackoverflow.com/questions/8032824/…

您是否安装了 Xcode 命令行工具？它位于“下载”下的 Xcode 首选项中。

感谢您的快速回复！我相信我拥有最新版本的 RVM。我刚刚安装了 Xcode 命令工具并再次尝试，但不幸的是没有运气。我也试过做“rvm get head”，同样的事情。我相信这可能与编译器有关，我不确定我是否安装了这个/如何安装它，如果有人可以请让我知道我可以做到并试一试。谢谢！
