RVM не может загрузить такой файл - win32/resolv (LoadError)

Question

Я использовал RVM для установки ruby ​​2.2.3. Он успешно установлен, но когда я запускаю gem install rails (или любой другой gem в этом отношении), он выдает мне эту ошибку:

$ gem install rails

Я использую Windows 10 Pro, Cygwin, rvm 1.27.0. На github RVM была старая открытая проблема ( https://github.com/rvm/rvm/issues/3519), которая выглядит очень похоже на то, что я получаю, но ответа так и не нашли.

Решение этой проблемы - убедиться, что вы установили libffi-devel также, а затем переустановите ruby. Таким образом, все необходимые гемы, такие как fiddle/win32, будут правильно установлены.

Я просто следовал тому же процессу, и он исправил это для меня в еще более новой версии Ruby: 2.3.1
