我的Authentication_pages_spec.rb文件：

我发现问题类似于Michael Hartl's Ruby on Rails Tutorial. Failed test in Chapter 9中显示的问题但这个解决方案在我的情况下不起作用。有人有想法吗？

Answer 1

也许只是空洞中的一个镜头，但你在SessionsHelper.store_location中输入错误。将“请求”更改为“请求”。

Answer 2

您的sessions_helper.rb文件包含拼写错误：requests而不是request。

请参阅：http://guides.rubyonrails.org/action_controller_overview.html#the-request-and-response-objects
