I'm trying to install Ruby on Rails on Ubuntu 11.10, but receiving this
$ sudo gem install rails
ERROR: While executing gem ... (Gem::DependencyError)
Unable to resolve dependencies: rails requires activesupport (=
3.2.3), actionpack (= 3.2.3), activerecord (= 3.2.3), activeresource (=
3.2.3), actionmailer (= 3.2.3), railties (= 3.2.3)
How can I fix this?
Note: Git (184.108.40.206 ) and Ruby (1.9.2p290) are installed properly.
