Я выполнил обновление с Rails 3.0.10 до 3.1.1, следуя этим инструкциям , и смог успешно запустить сервер rails с rails s, но столкнулся с ошибкой, как только я использовал RAILS_ENV переменные, отличные от development.
rails c работает, но rails c production, rails c test или любая другая пользовательская среда приводит к ошибке «Нет такого файла для загрузки - importenv (LoadError)».
