从rails 3.2升级到rails 4.2之前的测试套件
我最近试图将我的Rails应用程序从Rails 3.2更新到Rails 4.2。 在升级之前，我所有的测试套件都能正常运行，但更新之后，我收到了一些奇怪的东西。 每次我尝试运行测试时都会发生同样的错误

谁能帮我这个？
删除后，我得到另一个错误见

:(我做了渐进式更新从轨3.2到4.02，然后从4.02到4.1，所有工作顺利，然后在轨4.2我得到了同样的错误
我将这个问题发布在rails仓库的github上，他们回答我这是一个bug，将在4.2.1版本发布
目前你可以纠正这个问题。 行[关键] = value.gsub（ “$ LABEL”标签。to_s）如果value.is_a？（String）在从ActiveRecord的库文件fixture.rb 636线
