How can I install Ruby on Rails 3 on OSX?
- by Oluf Nielsen
Hey i got an White Macbook and, has to go in 10 hours to a conference. And I'm having a lot of problems.
First, I wanted to have Rails 3, so I used MacPorts to install Ruby 1.8.7. Tt worked well ;) 
So now I was thinking I should install Rails 3.. but no, no!.. it says..
  $ sudo gem install rails --pre
  
  ERROR:    Error installing rails:
  
                   activesupport requires Ruby version = 1.8.7.
So what can I do? I have 1.8.7 !
