Question

我正在将Rails 3.2应用程序更新为Ruby 2.2.2。我已经将Rails版本提升到3.2.22，这对Ruby 2.2.2来说是必要的。这相当不错，但促使黄瓜更新，从1.2.1升至1.3.20。（我不记得细节，因为那是几次失败的努力，但我认为我的功能正在通过，但在我这样做之前就退出了假。）

现在Cucumber功能运行良好（尽管有大量无关的Ruby 2.2.2警告），但rspec没有。具体来说，当我运行rake spec时，我收到此错误：

/path/to/gems/cucumber-1.3.20/lib/cucumber/rb_support/rb_dsl.rb:15:in `build_rb_world_factory': undefined method `build_rb_world_factory' for nil:NilClass (NoMethodError)

堆栈跟踪通过Capybara（2.4.4，由于其他原因固定），ActiveSupport和Bundler备份到rspec-core。

我尝试查找类似问题的所有搜索只会导致代码，因为它似乎是代码名称存在的唯一位置。

为什么我在运行rspec时从Capybara / Cucumber收到此错误？我该如何解决？

ETA：堆栈跟踪，路径缩小了一点：

我的预感是，有一个配置文件需要在某处重建。

从你的堆栈追踪 - capybara-screenshot宝石需要水豚/黄瓜，即使你正在运行不使用黄瓜的规格。这意味着从水豚/黄瓜对未经初始化的黄瓜调用世界，并给出错误。你正在使用的capybara-screenshot版本真的很旧，而且需要使用水豚/黄瓜的代码已被删除，所以你应该更新你正在使用的capybara-screenshot的版本，并添加

require 'capybara/cucumber'
require 'capybara-screenshot/cucumber'

到您的env.rb或其他黄瓜支持文件

rspec得到“未定义的方法`build_rb_world_factory'为nil”
