Rails測試將無法正常工作

試圖在railstutorial.org上執行Rails教程。我目前正在教程的測試部分，並且在執行測試時，我一直在收到錯誤。我用'生成StaticPages控制器'命令創建的測試文件是一樣的，我根本沒有修改它。當我在命令中輸入「軌道測試」我得到這個錯誤：Rails測試將無法正常工作

/Users/user/.rvm/gems/ruby-2.3.0/gems/actionpack-5.0.0.1/lib/abstract_controller/helpers.rb:152:in `rescue in block in modules_for_helpers': Missing helper file helpers//users/user/programming/odin/rails/sample_app/app/helpers/application_helper.rb_helper.rb (AbstractController::Helpers::MissingHelperError)

這裏是追溯：
