I started to learn Ruby on Rails while ago so now I am going back and starting again. I have found that I do not have rails installed but I do have jewellery box and ruby installed. Will installing the rails installer again effect these or just add rails?
Thanks
You just need to read about bundler. You may have any versions of any gems at the same time using bundler and rails currently (from v 3.0) build on top of bundler.
