我最近通过导轨5的升级工作，和我遇到了这个错误，当我尝试火起来的轨道控制台：导轨5升级：/actionpack-5.0.0/lib/action_controller/test_case.rb:49:in'初始化'：错误的参数数目（0 2）（引发ArgumentError）
/actionpack-5.0.0/lib/action_controller/test_case.rb:49:in initialize': wrong number of arguments (0 for 2) (ArgumentError)
目前bundle update rails已与解决足以做更新5.0.0 gem依赖完成后，rspec的运行（尽管有很多休息时间我正在修复）。我也可以在没有错误的情况下运行rails s。
