Ruby Guard получает: Обычно разрешено только одно использование каждого адреса сокета. Ошибка::EADDRINUSE

Я работаю над главой 3.6 Учебника по Rails, поэтому я пытаюсь реализовать Rspec, Guard и Spork. На данный момент кажется, что все работает, но меня мучает ошибка EADDRINUSE при запуске Guard. Моя среда — Windows 8 x64, BiNami Rubystack 1.9.3-6, Ruby 1.9.3p392, Rails 3.2.13 и RubyMine 5.4.2. Такая же ошибка возникает либо в RubyMine, либо в CLI.

Я использовал netstat для проверки того, что порты не используются до запуска Guard и после завершения работы Guard. Таким образом, гвардия кажется единственным фактором. Я искал похожие проблемы и убедился, что не нашел ни одной проблемы. Я попытался минимизировать свою среду, чтобы изолировать проблему, но безуспешно. Например, я попытался устранить лишние драгоценные камни, а также попытался сделать те, которые были указаны, универсальными без указания версии. Ничто из того, что я сделал, не имело никакого значения.

Мой гемфайл:
