After a couple of hours of not getting "/usr/bin/env: ruby: No such file or directory" error and google searching, I uninstalled my system ruby 1.8.7 (I also had 1.9.3 installed via rvm) by doing sudo apt-get purge ruby rubygems.
I have been struggling this task. I have been developing in php but want to witch to ruby. My goal is to install ruby and then a IDE for ruby AND then a debugger. is there a ruby stack like LAMP? I have installed rvm succesfully (no rails). However I do not know how to even create a HelloWorld script after installing. do i use a text pad or the command line?
