Hey Guys, This is probably not specific to Rails, but I'm kinda hoping someone already faced this error, it's been hours trying to debug the issue, but I just can't figure out why it's happening
So the application I'm developing is on Rails 3.1 using the 3-1-stable branch,
up-to-date, and I'm using latest version of all the Gems listed in the Gemfile
below..
When I run guard with the guard-spork portion commented, everything works just
fine, however, if I enable spork, I get the following error on the second time
the tests run, that's right, the first time the tests run like usual but If I
save/touch any of the test file, rspec gets invoked and the following error is
shown (all the tests fail of course).
Any hints?
Regards,
Wael
