ruby on rails: неопределенный метод "version_requirements" при попытке запустить сервер после новой установки

Мне недавно пришлось недавно установить ruby ​​на рельсы. Когда я попытался запустить сервер для проекта, над которым я уже работал до этой новой установки, я получил следующую ошибку: 

$ ruby script/server
=> Booting WEBrick...
./script/../config/../vendor/rails/railties/lib/rails/gem_dependency.rb:107:in `requirement': undefined method `version_requirements' for #<Gem::Dependency:0xb74bf764> (NoMethodError)

    from script/server:3

У меня есть последние версии ruby, rubygems и rails.

Есть предложения?

Спасибо.

Похоже, вы используете более новую версию rubygems со старой версией rails.

Вот решение: https://gist.github.com/807008
