在RHEL 6.2环境中尝试在RubyMine-7.0.2 IDE上进行调试时，我遇到了错误。

除此之外，当我尝试通过执行以下命令安装gems时，我得到了像

-bash:apt-get command not found.
安装rubygems的命令。
aptitude install libgemplugin-ruby
apt-get install libgemplugin-ruby
如果有人可以帮助我，我将不胜感激。

您正尝试在RHEL框中使用Ubuntu包实用程序（apt / aptitude）。只需按照正确的教程（例如this one）安装rubygems：
yum install rubygems
