Hey there,

Im running on Ubuntu 9.1.

I’ve installed rspec gems, cucumber gems.

When trying to run the features, I’m getting an error , it seems to be  
the  
TestUnit, which is not installed.

$rake cucumber features -n

rake aborted!  
Could not find RubyGem test-unit (= 1.2.3)  
/store/workspace/atom-commerce/Rakefile:10:in `require’

if I install test-unit, its a different version.

rake aborted!  
RubyGem version error: test-unit(2.0.6 not = 1.2.3)  
/store/workspace/atom-commerce/Rakefile:10:in `require’

What should I do? I’ve searched everywhere, can’t find answers.

Any might be able to help me.

Regards  
Rodrigo D.

Rodrigo, you need to install test-unit-1.2.3:

sudo gem install test-unit -v=1.2.3

Good luck,
