Почему при развертывании на новом сервере Heroku возникает ошибка зависимости nokogiri и mini_portile2?

Question

Я пытаюсь обновить приложение RoR для запуска на новом сервере Heroku. Я продолжаю получать ошибку:

'Downloading nokogiri-1.10.3 revealed dependencies not in the API or the lockfile
remote:        (mini_portile2 (~> 2.4.0)).
remote:        Either installing with `--full-index` or running `bundle 
update nokogiri` should
remote:        fix the problem. '.  

И мини_портили2, и нокогири появляются в Gemfile и Gemfile.Lock. Он работал нормально, используя старые версии на старых серверах. Новая версия работает для меня дома, используя rails server, не показывая проблем с зависимостями. Я проверял и проверял зависимости столько, сколько знаю, и следовал совету Heroku по установке с --full-index и запуску комплекта обновления nokogiri. Что мне нужно сделать, чтобы это работало? Я использую последнюю версию Cygwin и последние версии Ruby и Rails с верными верностями. Windows 7.

1. bundle install --full-index # без изменений
2. bundle update nokogiri # без изменений
3. gem install nokogiri # без изменений
4. gem install nokogiri --system-dependencies # без изменений
5. gem install nokogiri -- --use-system-libraries --with-xml2-config=/usr/include/libxml2 --with-xslt-config=/usr/include/libxslt # nochange
6. В Gemfile я попытался поставить mini_portile2 самостоятельно и в производственной группе. # без изменений

После каждой установки gem я обновляю / устанавливаю пакет.
