升级到Mavericks后，libyaml可能存在问题或与xcode相关的问题：
$ xcode-select --install # if you upgraded to Mavericks
$ brew update # if using homebrew
$ rvm get head # to get lastest rvm
$ rvm pkg install libyaml
$ rvm pkg install readline
$ rvm reinstall all --force
其他可能性是~/.gemrc
如果这些都不起作用，请为OSX尝试rvm GUI ruby manager（免费）或为您设置RVM的RailsInstaller。
