Я работаю в рулонах Hartl ruby on rails (раздел 2.2), и мне не удается выполнить миграцию базы данных. Все, казалось, работает, а затем я побежал rails generate scaffold User name:string email:string. После этого я попытался запустить пакет exec rake db: migrate и получил следующее сообщение об ошибке:
$ bundle exec rake db:migrate
== 20141125234257 CreateUsers: migrating ======================================
-- create_table(:users)
-> 0.0079s
== 20141125234257 CreateUsers: migrated (0.0080s) =============================
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

Я попытался вернуться к предыдущей фиксации и снова запустить все, но я получаю такое же сообщение об ошибке. Есть ли еще файлы, которые я должен добавить, которые могут помочь с этим?
