Trouble installing Cucumber into Rails 3

[steven_noble]

After previously having used and enjoyed Cucumber under Rails 2.x, I'm
try to get it up and running on Rails 3.

My Gemfile includes:

group :development, :test, :cucumber do
gem "compass", ">= 0.10.5"
gem "compass-susy-plugin", ">=0.8.1"
gem "haml"
gem "gherkin"
gem "mongrel"
gem "rspec-rails", ">= 2.0.0"
gem "capybara"
gem "cucumber", ">=0.7.3"
gem "cucumber-rails"
gem "database_cleaner"
gem "launchy" # So you can do Then show me the page
gem "spork"
gem "sqlite3-ruby", :require => "sqlite3"
gem "webrat"
end

When I try to generate Cucumber, I get the error/trace that I've
pasted below. What should I do next?

Many thanks,

Steven.

Hi Steven,

This is a guess, but try taking gherkin out of your gemfile. It's probably requiring an older version of gherkin. Gherkin should be implicitly required by Cucumber anyway.

cheers,
Matt

Hi Matt,

Actually I put it in because on Stack Overflow I saw that suggested to
someone with a similar problem.

http://stackoverflow.com/questions/3556147/rails-3-cucumber-load-error

I've just removed it and confirmed the problem remains.

Cheers,

Steven.

Can you try it with the latest version of Cucumber (0.9.x) please?

Good point. Updated Gemfile and Cucumber. Now I get:

steven$ rails generate cucumber:install --rspec --capybara --spork

Could not find generator cucumber:install.

Many thanks,

Steven.

Do you still have cucumber-rails in there? You need it.

[steven_noble]

Indeed. Gemfile includes:

group :development, :test, :cucumber do
gem "compass", ">= 0.10.5"
gem "compass-susy-plugin", ">=0.8.1"
gem "haml"

gem "mongrel"
gem "rspec-rails", ">= 2.0.0"
gem "capybara"

gem "cucumber", ">=0.9.2"

gem "cucumber-rails"
gem "database_cleaner"
gem "launchy" # So you can do Then show me the page
gem "spork"
gem "sqlite3-ruby", :require => "sqlite3"
gem "webrat"
end

I don't understand that. I just tried that Gemfile on a brand new Rails 3.0 app and `rails g --help` shows the cucumber:install generator.

Daft question, but did you remember to do `bundle install` after you changed the gemfile that last time?

Thanks Aslak. The gems are all in the :development group in my
Gemfile.

Matt, yes indeed I have run bundle install. :-)

I also get:

steven$ rails g --help
Usage: rails generate GENERATOR [args] [options]

General options:
-h, [--help] # Print generator's options and usage
-p, [--pretend] # Run but do not make any changes
-f, [--force] # Overwrite files that already exist
-s, [--skip] # Skip files that already exist
-q, [--quiet] # Suppress status output

Please choose a generator below.

[steven_noble]

I see the answer. Because I had an older version of Cucumber, my
generator is cucumber:skeleton not cucumber:install.
