【问题描述】：

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 控制台时，我得到如下错误

/.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)

由于我无法运行 rails 控制台，您能否提出任何解决方案来消除此错误。

完整的错误跟踪是

请显示完整的错误跟踪，而不仅仅是单行。
我用错误跟踪编辑了我的问题。

【解决方案1】：

您可能正在运行 draper gem ？

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

Draper 和 Rails 5 之间存在问题。使用主分支

The correct location is now: gem 'draper', github: 'drapergem/draper'
the rails-5 branch has been merged into master and no longer exists
