Question

I’m trying to install Spree following their guide here : http://guides.spreecommerce.com/getting_started.html

I’m stuck on a weird problem :

    /usr/lib/ruby/vendor_ruby/active_support/inflector.rb:407: uninitialized constant ActiveSupport::CoreExtensions (NameError)

I’m using Ubuntu Server 12.04 and Rails 3.2.9.

Thanks for the help.

As @RyanBigg suggested that was a version problem of rails. The solution was to uninstall the rails version of APT and to install it through gem, while focusing on setting up the exact version mentionned in the spree installation guide :

sudo aptitude remove
gem install rails -v 3.2.3

Opposed to what you might think the APT version was “too recent” (3.2.9).
