Answer 1

I had the same problem with rails 3.1. The solution was to put the following lines in my GEMFILE:
# ===:git with the repository's url that works=== #
gem 'spree', :git => 'git://github.com/spree/spree.git'
This should help in your case, too.

#jhsilva007 : Specifying this line ( gem 'spree', :git => 'git://github.com/spree/spree.git' )
definitely helped me resolving of error.
I think this line will get the latest version of the spree from github. What if I just want the particular version number of spree. I mean I don't like to get the beta version.
