Question

我正在使用Rails 3.1应用程序，我正在将黄瓜集成到我的应用程序中，但是当我尝试运行它时，我得到了这个奇怪的错误，有人可以帮助我吗？

Using the default profile...

这是我的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

这是我的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

谢谢！：）

Answer 1

我有同样的问题并解决了将cucumber-rails升级到1.0.5的问题。在Gemfile中试试这个。

gem "cucumber-rails", "1.0.5"

重新运行安装程序

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

Answer 2

我遇到了类似的问题，我相信它的RVM导致了这个问题。

基本上它是针对Ruby编译的依赖项;使用rvm笔记

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

以上是MRI

如果未安装任何这些，请安装它们，然后卸载/安装1.9.2-p180

希望有所帮助

Answer 3

对我而言，魔力是require: false

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

Cucumber Rails 3.1未初始化的常量ActionController :: Dispatcher（NameError）
