First time installing RoR and things are a bit confusing.
I first installed Ruby through apt-get only to realize that this is not way to go. After Installing ruby and rails with RVM, I ran into trouble with Readline. Fixed it by following troubleshooting steps. I thought that I got everyting working. I was wrong.
Now that I opened new shell and typed $ ruby, I got:
ERROR: Missing RVM environment file: '/home/user/.rvm/environments/ruby-1.9.2-p180'
There is no such file. What has happened? Should I just rm my .rvm directory and start anew? What did I do wrong?
