问题
I am trying to install Rails 2.3 gem on my Fedora server. The application is not having Gemfile in it. It requires oauth2 gem. When I use the installation command it is giving the following error:
rake aborted!
can't activate rack (>= 1.1.0, < 2, runtime) for ["faraday-0.5.7", "oauth2-0.1.0"], already activated rack-1.0.1 for ["actionpack-2.3.5", "rails-2.3.5"]
Is there any way to find what are the required gems for the Rails 2.3.5 gem?
