Question

I’m trying to get Rails 3.0.x installed on my machine. The first time i tried it, it gave me the following error: cant find lib . So i found the rails3.0.3 gem folder and made the lib folder. I can install the gem correctly but when i type the following command rails -v It throws the following error.

Daniel-MacBook-Pro:~ Daniel$ sudo gem install rails

probably you do not have rdoc installed. It does not hamper any functionality during development. If if you do want you can try this

   sudo gem install rdoc
