安装Ruby 1.9.3-p374时配置错误

如果能在Mountain Lion OS X上安装Ruby 1.9.3-p374，我将不胜感激

我是ruby新手，目前正在尝试从1.8.7升级，但每当我在命令行中输入rvm install 1.9.3-p374时，我会得到：

user-macbook-pro-2:~ user$ rvm install 1.9.3-p374

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.

ruby-1.9.3-p374 is not installed.
To install do: 'rvm install ruby-1.9.3-p374'

对于如何解决这一问题的任何帮助，我们将不胜感激。错误部分复制如下：

  Error running './configure --enable-shared --disable-install-doc --prefix=/Users/user/.rvm/rubies/ruby-1.9.3-p374 --with-opt-dir=/Users/user/.rvm/usr', please read /Users/user/.rvm/log/ruby-1.9.3-p374/configure.log

    ruby-1.9.3-p374 is not installed.

configure.log读取

在尝试更新之前，我已经安装了xcode，但在2012年11月安装了用于xcode的命令行工具OS X Mountain Lion，21423似乎已经整理好了-感谢大家的建议

configure.log中有什么内容？您应该安装XcodeTo安装程序：“rvm install ruby-1.9.3-p374”您尝试过吗？您运行过“rvm requirements”吗？这将为您提供安装前所需的软件包列表。使用rvm时，Xcode的较新版本可能会比较棘手。查看相关信息。在尝试更新之前，我已经安装了xcode，但是安装命令行工具OS X Mountain Lion for xcode-2012年11月，21423似乎已经解决了问题-谢谢大家的建议
