It seems that most rake db tasks fail. Tasks don't break when using Ruby 1.9.2.

Hello,

I'm not sure that would help a lot, but I got the same issue with Ruby 1.9.3p0, Rails 3.0.11, Rake 0.9.2.2 on every tasks when RAILS_ENV is set to "test". And like in your example, it works with Rails 1.9.2.

Hey,

I figured that with regards to tasks, db migration etc., 1.9.3 looks like it blew up and failed to finish the task but it actually completed.
I tried to do rake db:migrate on mine, it still showed the same 'block in non_options' error but actually it finished the migration.

Have you seen this?
https://github.com/jimweirich/rake/issues/51

I still haven't found a way to fix these errors though.

Like beanieboi, I used shoulda which produces this error. I found that the require 'test/unit' call used in shoulda 2.11.3 and shoulda-context re-runs tests on Ruby 1.9.3. If I comment this line, it seems to work (I tested that with shoulda only).

For now, I fixed the issue by removing shoulda from my Gemfile and by including the code I need from shoulda-context. It's quite ugly, but I'll try to find a better way.

Thank you for the link which helps me.

I have the same problem and have verified it's a problem with shoulda interaction.

I also ran into this issue - removing shoulda fixed it. Many thanks!

It's worth pointing out that declaring :require => false in your Gemfile will avoid this problem:

gem "shoulda", :require => false

Then just make sure you require "shoulda" in your spec helper file.

Yes. It helped! Thank you!

This was helpful. Thank you!

cool~ flavorjones' solution works quite well.

I ran into this issue with flexmock as well--same fix
