【问题描述】：

我是 Rails 新手，在使用 Cucumber 运行测试时遇到了麻烦。我收到以下错误：

You have already activated activesupport 3.1.0, but your Gemfile requires activesupport 3.1.0.rc8. Consider using bundle exec. (Gem::LoadError)

我的 gemfile 如下所示：

source 'http://rubygems.org'

gem 'rails', '3.1.0.rc8'

group :assets do
  gem 'sass-rails', "  ~> 3.1.0.rc"
  gem 'coffee-rails', "~> 3.1.0.rc"
  gem 'uglifier'
end
gem 'jquery-rails'
gem "therubyracer", ">= 0.8.2"
gem "haml", ">= 3.1.2"
gem "haml-rails", ">= 0.3.4", :group => :development
gem "rspec-rails", ">= 2.6.1", :group => [:development, :test]
gem "guard-rspec"
gem "database_cleaner", ">= 0.6.7", :group => :test
gem "mongoid-rspec", ">= 1.4.4", :group => :test
gem "factory_girl_rails", ">= 1.1.0", :group => :test
gem "cucumber-rails", ">= 1.0.2", :group => :test
gem "capybara", ">= 1.0.1", :group => :test
gem "launchy", ">= 2.0.5", :group => :test
gem "bson_ext", ">= 1.3.1"
gem "mongoid", ">= 2.1.9"
gem 'devise', :git => 'git://github.com/plataformatec/devise.git', :branch => 'master'
gem "frontend-helpers"
gem "rails-footnotes", ">= 3.7", :group => :development
gem "barista"
gem "sunspot"
gem 'sunspot_rails'
gem "sunspot_mongoid"
gem 'vinova_sunspot_mongoid', :require => 'sunspot_mongoid'
gem "fakeweb", "~> 1.3.0"
gem "sunspot_matchers", "~> 1.2.1.4"

Cucumber 以前可以工作。我最近添加了 sunspot 并升级到 rails 3.1.0.rc8。我不明白 bundle exec 消息。

谢谢

【问题讨论】：

你试过用 bundler 运行 cucumber 吗？
试过 'bundler exec cucumber features' 并且成功了，但为什么我不能再从命令 'cucumber features' 运行它了？
因为您的机器上安装了多个版本的 rails。这正是 bundler 解决的依赖问题：D
@lucapette 您可能应该将此作为答案发布，因此可以关闭此线程。 :)
@RazokKull 感谢您的建议！完成！

【解决方案1】：

试试：

bundler exec cucumber features

它应该可以正常工作。请参阅docs 了解更多信息。

【解决方案2】：

这对我有用：

bundle exec cucumber features

bundle exec cucumber features/filter_movie_list.feature

第一个用于所有功能，第二个用于某些功能。
