Cucumber Rails 3.1 uninitialized constant ActionController :: Dispatcher (NameError)

I am using a Rails 3.1 application and I integrated the cucumber into my application, but when I try to run it, I get this strange error, can someone help me?

Using the default profile... uninitialized constant ActionController::Dispatcher (NameError) /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-rails-0.3.2/lib/cucumber/rails/action_controller.rb:51:in `rescue in <top (required)>' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-rails-0.3.2/lib/cucumber/rails/action_controller.rb:42:in `<top (required)>' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-rails-0.3.2/lib/cucumber/rails/world.rb:27:in `<top (required)>' /Users/chinog9/INNKU/tacos/features/support/env.rb:11:in `<top (required)>' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/rb_support/rb_language.rb:143:in `load' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/rb_support/rb_language.rb:143:in `load_code_file' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime/support_code.rb:176:in `load_file' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime/support_code.rb:78:in `block in load_files!' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime/support_code.rb:77:in `each' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime/support_code.rb:77:in `load_files!' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime.rb:137:in `load_step_definitions' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/runtime.rb:39:in `run!' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/cli/main.rb:43:in `execute!' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/lib/cucumber/cli/main.rb:20:in `execute' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/gems/cucumber-0.10.2/bin/cucumber:14:in `<top (required)>' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/bin/cucumber:19:in `load' /Users/chinog9/.rvm/gems/ruby-1.9.2-p180/bin/cucumber:19:in `<main>'

Here is my env.rb:

 ENV["RAILS_ENV"] ||= "test" require File.expand_path(File.dirname(__FILE__) + '/../../config/environment') require 'cucumber/formatter/unicode' # Remove this line if you don't want Cucumber Unicode support require 'cucumber/rails/world' require 'cucumber/rails/active_record' require 'cucumber/web/tableish' require 'capybara/rails' require 'capybara/cucumber' require 'capybara/session' require 'cucumber/rails/capybara_javascript_emulation' # Lets you click links with onclick javascript handlers without using @culerity or @javascript Capybara.default_selector = :css ActionController::Base.allow_rescue = false Cucumber::Rails::World.use_transactional_fixtures = true if defined?(ActiveRecord::Base) begin require 'database_cleaner' DatabaseCleaner.strategy = :truncation rescue LoadError => ignore_if_database_cleaner_not_present end end

And here is my gemfile:

 source 'http://rubygems.org' gem 'rails', '3.1.0.rc4' gem 'sqlite3' gem 'nifty-generators' gem 'sass-rails', "~> 3.1.0.rc" gem 'coffee-script' gem 'uglifier' gem 'jquery-rails' gem 'ruby-debug19', :require => 'ruby-debug' group :development, :test do gem 'capybara' gem 'database_cleaner' gem 'cucumber-rails' gem 'cucumber' gem 'rspec-rails', '>=2.6' gem 'rspec-rails-mocha' gem 'spork', '~> 0.9.0.rc' gem 'factory_girl_rails' gem 'launchy' gem "ruby-debug19" gem 'turn', :require => false gem "selenium-client" end gem "mocha", :group => :test

Thanks!:)

I had a similar problem and I think its RVM is causing the problem.

Mostly its Ruby dependencies are compiled; using rvm notes

 sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev

The above applies to MRI

If any of them is not installed, install them, then remove / install 1.9.2-p180

Hope that helps

I had the same problem and decided to upgrade the cucumber rails to 1.0.5. Try this in the gemfile.

 gem "cucumber-rails", "1.0.5"

And re-installer

 script/rails g cucumber:install your-language --your-options

For me, magic was require: false

 gem 'cucumber-rails', '~>1.4.0', require: false
