Error when trying to start server after upgrading to Rails 3

Question

I\'ve just upgraded to Rails 3, using the instructions from this railscast. When I try to start the server, this is what happens:

$ rails s
script/rails:6:in         


        

Answer 1

Have you actually installed the rails 3.0.x gem? Maybe you missed this step :).

It looks like your script/rails script cannot find the included file from rails gem. You need to install all needed gems separately for each version of Ruby you're using (e.g. 1.8.7 and 1.9.2).
