грабли прерваны! undefined метод `igration_error = 'для ActiveRecord :: Base: Class
Я занимаюсь разработкой проекта на Ruby on Rails. До настоящего момента я использовал Rails 4, и все было хорошо, прежде чем я столкнулся с проблемами неспособности с гемами. Я решил откатиться на Rails 3, изменил мой Gemfile, удалил Gemfile.lock, все установки rails и railties. Затем я запускаю bundle install и устанавливаю Rails 3.2.13. Однако теперь, когда я запускаю rake db: создать все еще хорошо. Когда я запускаю rake db: migrate, начинаются проблемы:
JeffreeBook:llvoo kristijonas$ rake db:migrate
WARNING: Nokogiri was built against LibXML version 2.8.0, but has dynamically loaded 2.7.8
rake aborted!
