[Alex Le]

running

rake assets:precompile --trace

with shoulda and Ruby 1.9.3-p125 with Rails 3.2.3 throw this error:

I was following a different thread here, jimweirich/rake#51, and after commenting out shoulda, I was able to run rake asset:precompile successfully.

This is still a problem with 1.9.3-p194.

A slightly nicer fix is to change the Gemfile line to gem 'shoulda', :require => false and then add require 'shoulda'to spec_helper.rb.

I say nicer because then you don't have to keep commenting and uncommenting the Gemfile each time you want to test or run a rake task.

If you are using rspec and not Test::Unit, please use shoulda-matchers instead of shoulda. shoulda is for Test::Unit.

[Phil Hale]

Thanks. There are still plenty of tutorials around that say to add "gem 'shoulda'" - i know it's pretty clear already on the read me but you might want to make that more prominent. Thanks for letting us know :)
