Может ли кто-нибудь помочь мне исправить это?

Попробуйте добавить эту строку в свой Gemfile

gem 'rack', '~> 1.6.4'

а затем запустите:

bundle install 

и посмотрите, решит ли это вашу проблему.

Обновлять

Если вышеуказанное не работает, попробуйте удалить railties gem. Затем установите более старую версию rails (в учебнике использовалась версия 4.0.0 для рельсов). Проблема связана с несоответствием/несовместимостью версий некоторых ваших драгоценных камней.

Посмотрите на это: stackoverflow.com/questions/31766656/ Похоже, это та же проблема, что и у вас. Тот же учебник, а также. - person K M Rakibul Islam; 05.09.2015
