rake aborted! undefined method `migration_error=' for ActiveRecord::Base:Class

Question

I am developing project on Ruby on Rails Till the present moment I used Rails 4 and everything was fine before I faced incapability issues with gems. I decided to rollback to Rails 3, changed my Gemfile, removed Gemfile.lock, all rails installations and railties. Then I run bundle install and installed Rails 3.2.13. However now when I run rake db:create everything is still fine. When I run rake db:migrate the problem begin:

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!

How to resolve it?Everything is fine with db config

Answer 1

Rolling a Rails 4 project back to Rails 3 caused this error for me. Deleting the following line from config/environments/development.rb fixed the issue:

config.active_record.migration_error = :page_load
