无法在RVM上切换另一个红宝石版本

Question

我在Ubuntu 12.04上有Yakuake，而我之前遇到过this problem，它已经解决了。但是现在我无法在RVM上从Ruby切换到JRuby。当我运行rvm use jruby它抛出这个错误：

RVM is not a function, selecting rubies with 'rvm use ...' will not work. 

You need to change your terminal emulator preferences to allow login shell. 
Sometimes it is required to use `/bin/bash --login` as the command. 
Please visit https://rvm.io/integration/gnome-terminal/ for a example.

感谢Mikey，加入source ~/.rvm/scripts/rvm到.zshenv - 因为正在使用zsh在Yakuake-摆脱这一问题的。
