Ruby Rspec任意\u实例存根导致错误未定义方法\uu Rspec\u原始\u dup

我试图为该类的任何实例（通过任何_实例）删除一个类方法。我的测试成功运行，但在测试结束时，当rspec尝试重置any_实例存根时，它抛出一个错误（无法从回溯中找到匹配行）。下面是明显的罪魁祸首代码行（删除它会删除错误）：

完整错误如下所示。似乎存根本应（但未能）创建_rspec_original_dup方法，当重置发生时，它找不到预期的方法

我通过简单地使用Rspec v2.10.0而不是v2.11.0解决了这个问题：

gem 'rspec', '~> 2.10.0'

从Henrik提供的链接来看，听起来他们可能会发布Rspec的错误修复。关注更多信息。与此同时，降级为我解决了这个问题

（感谢您帮助我解决这个问题，Henrik。）

看起来您正在使用OSX系统Ruby。如果使用RVM或rbenv，它是否有效？我问这个问题是因为我们看到了相同的行为，但只适用于运行OSX系统Ruby的开发人员。升级到RSPEC2.11后得到了类似的结果。我使用的是RVM中的Ruby 1.9.3，不过是在OSX上，如果这与此相关的话。我执行

ThinkingSphinx:：Search.any_instance.stub（：error）

并获取类'ThinkingSphinx:：Search'的错误

未定义的方法'dup'，回溯中有以下内容：
/Users/henrik/.rvm/gems/ruby-1.9.3-p0-patched@foobar/gems/rspec-mocks-2.11.1/lib/rspec/mocks/any_instance.rb:64:in'alias_method'
。创建了一个问题：
gem 'rspec', '~> 2.10.0'
