I have spent hours trying to get some version of Rails installed and all to 
no avail. It seems there are many people who get the same errors but nobody 
seems to have any answers.  

I am new to both Rails and Ubuntu.  This is where I am trying to set it 
up.  

Most recently I went to rubyonrails.org and it suggests to use Rails 4.0 
and Ruby 2.1 and to use rbenv to install rather than RVM.  

It says it installed it but then it doesn't work.  

When I type: ruby -v 

I get...

rbenv: ruby: command not found

The `ruby' command exists in these Ruby versions:
  2.1.0

What is this telling me?  It says it isn't found and that it does exist.  
Huh?  

Why is this so difficult?  Any insights to help me get my head around all 
of this would be most welcomed.
