我猜你没有通过 rvm 安装 ruby​​ 所需的包(依赖项)。以下步骤应该可以帮助您:

yum install gcc-c++ patch readline readline-devel zlib zlib-devel 
yum install libyaml-devel libffi-devel openssl-devel make 
yum install bzip2 autoconf automake libtool bison iconv-devel
curl -L get.rvm.io | bash -s stable
source /etc/profile.d/rvm.sh
rvm install 2.1.2
rvm use 2.1.2 --default

现在检查你的 ruby​​ 版本:

ruby --version
