Problem with installing Rails 2.3.8 on Ubuntu 10.04

hi,

I installed the ruby-full package. After downloading the rubygems 1.3.7, I installed it without any problem. I guess it should have installed relative gems by default, such as activesupport. Any help is appreciated.

Hi,

now you have rails 2.2.3 installed, the easyest way is to run the following command : (with sudo if needed) "gem update rails" : will only update the rails gem "gem update --system" : will update all your installed gems to the last stable version
