我无法使用Surveyor gem设置简单的rails调查。我在新的rails项目中遵循此处给出的基本说明：http://nubic.github.io/surveyor/
另外，我的gemfile包含以下内容以处理rails 4问题：
gem 'surveyor', :git => 'git://github.com/NUBIC/surveyor.git', :branch => 'rails4'
gem 'formtastic'
当我尝试运行演示调查（厨房水槽）时，我最终得到以下错误：
NoMethodError in SurveyorController#edit
undefined method `with_sections_and_questions' for #<Class:0x007fe84d519450>
如何解决这个问题？
解决方案：我已经向测量师的作者提交了一份错误报告。似乎gem还在等待rails 4的升级。与此同时，这个开发分支可以用来推动事情发展：
gem 'surveyor', github: 'caboteria/surveyor', branch: 'rails4'
gem 'protected_attributes'

答案 0 :(得分：0)
错误：
undefined method `with_sections_and_questions' for #<Class:0x007fe84d519450>
表示类Class没有实例方法#with_sections_and_questions。您应该在方法#with_sections_and_questions上搜索项目中涉及的所有宝石。尝试搜索如下：
grep with_sections_and_questions /usr/local/rvm/gems/ruby-2.0.0-p247/bundler/gems/ -r
如果grep没有找到类似于以下方法的定义：
def with_sections_and_questions
您必须在issue page上向开发人员提出问题。
