Rails控制台出现错误:参数数错误(给定0，预期为2) (ArgumentError)

Question

我使用的是ruby版本2.3.1和rails版本5.0.0

当我尝试运行rails控制台并得到错误时，如下所示

/.rvm/gems/ruby-2.3.1/gems/actionpack-5.0.0.1/lib/action_controller/test_case.rb:49:in `initialize': wrong number of arguments (given 0, expected 2) (ArgumentError)

如果我不能运行rails控制台，请您提供任何解决方案以消除此错误。

完全错误跟踪是

你可能在经营draper宝石公司？

看看Ruby on Rails 5.0 upgrade not working with rails console or db:migrate

Draper和Rails 5之间有一个问题。

正确的位置现在是: gem 'draper'，github：'drapergem/draper‘rails-5分支已经合并到master中，不再存在了
