I have Active Support 3.0.3 installed and Rails 3.0.3 with Ruby 1.8.7.
When I try to use 1.week.ago
I get
NoMethodError: undefined method 'week' for 1:Fixnum
from (irb):2
The other core extensions seem to work. I tried it on a friend's computer (same install specs and legacy versions are on his) with the same results.
What gives?
All of this is in IRB.
