How to install Ruby on Rails 3.0 on Ubuntu 10.10?

Question

After installing Ruby and Ruby Gems:

$ sudo apt-get install ruby rubygems
...
$ ruby -v
ruby 1.8.7 (2010-06-23 patchlevel 299) [i686-linux]
$ gem -v
1.3.7
         


        

Answer 1

try installing the rdoc gem first:

gem install rdoc

It worked for me using RVM on ruby 1.8.7 and rails 3.0.7

Good luck.
