rvm无法安装任何ruby

在任何版本的ruby安装过程中，RVM都会给我一个错误。 举个例子，ree-1.8.7-head

rasfast@rasfast-home:~$ rvm install ree-1.8.7-head Installing Ruby from source to: /home/rasfast/.rvm/rubies/ree-1.8.7-head, this may take a while depending on your cpu(s)... ree-1.8.7-head - #fetching Cloning from git://github.com/FooBarWidget/rubyenterpriseedition187-330, this may take a while depending on your connection...
