Im taking over a project someone started a while ago. Im having a little bit of a difficult time because its Rails 2, and i have only learned rails 3.
Im trying to install a gem ive used frequently, but the newest version is for rails 3. The github page says for rails 2, use version .1. But i do not know how to install an older version (especially since rails 2 has no Gemfile)! Can someone help? Heres the github:https://github.com/cschiewek/devise_ldap_authenticatable/tree/0.4.9 Any suggestions?
Go to the config/environment.rb file and add a line such as this:
Change gem name and version number to fit your needs.
