我最初使用安装程序从这里安装了ruby 1.9.3：http://railsinstaller.org/ 现在我想安装Ruby 2.0和Rails 4
所以我使用安装程序已安装的rvm女巫
rvm install 2.0.0
但是失败了：

You can get help using IRC: http://webchat.freenode.net/?channels=rvm
日志报告了这个：
[2013-03-29 01:34:58] requirements_port_libs_install
/ usr / local / rvm / scripts / functions / logging：第141行：requirements_port_libs_install：找不到命令
跑完之后：
rvm requirements
但是使用相同的消息和日志失败了 我读到这可能是我的xCode编译器版本的问题，所以我从应用程序商店下载了新版本，并从那里安装了命令行实用程序，仍然是相同的消息。
我知道这不是一个有趣的问题，但非常感谢帮助。
