To fix the following error:
undefined method `fork=' for #<Cucumber::Rake::Task:0xb770bab8>
You need to upgrade cucumber, rspec and rspec-rails.
$ gem install cucumber
$ gem install rspec
$ gem install rspec-rails
If you run into the following error:
cucumber database is not configured (ActiveRecord::AdapterNotSpecified)
Then you should run the cucumber script to update your database.yml file:
$ script/generate cucumber
If are getting the following error after your run “cucumber features”
no such file to load -- spec/test/unit
Then you may need to install or upgrade “hoe” gem, U’ not sure though, but it worked for me.
$ gem install hoe
Can’t you install “factory girl” with the following command?
$ gem install thoughtbot-factory_girl
Why not adding Github’s gem archive to your gem source list?
$ gem sources -a http://gems.github.com
$ gem install thoughtbot-factory_girl
You upgraded to cucumber 0.3.103 and webrat 0.5.3, you run your features and get the following error:
undefined method `use_transactional_fixtures' for Cucumber::Rails:Module (NoMethodError)
./features/support/env.rb:32
It is easy to fix. Replace
Cucumber::Rails.use_transactional_fixtures
with
Cucumber::Rails::World.use_transactional_fixtures = true
You fixed the error above, but this time you see the following error:
undefined method `bypass_rescue' for Cucumber::Rails:Module (NoMethodError)
./features/support/env.rb:37
Replace
Cucumber::Rails.bypass_rescue
with
ActionController::Base.allow_rescue = false
By the way, why don’t you just create a new features/support/env.rb by running the following command?
$ ./script/generate cucumber
So, you upgraded to cucumber 0.3.103 and you tried to run a feature with “—tags” or “-t” parameter like the following:
$ cucumber -r features/ -t focus features/feedback.feature
And you get the following error:
0 scenarios
0 steps
0m0.000s
You have a nil object when you didn't expect it!
You might have expected an instance of ActiveRecord::Base.
The error occurred while evaluating nil.[] (NoMethodError)

It is obvious that none of your scenarios run, why? Because as “aslakhellesoy” said: “you have to use -t @focus since 0.3.102”. But don’t worry, he also added that he was going to hack the code to display you a friendly message if you try to use tags without “@” symbol. So, to get rid of the error above, run your tagged feature like this:
$ cucumber -r features/ -t @focus features/feedback.feature
aslakhellesoy kept his promise and updated Cucumber to display a friendly message in case you use ‘-t’ parameter withouth ‘@’ symbol. Related commit can be found here
