我刚刚开始学习rails并且创建了一个注册页面，我使用了＆＃34; gem devise＆＃34;，当我运行rake db：migrate时，我得到以下错误
C:\Sites\code\omrails>rake db:migrate

rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:

如果有人能帮助我克服这个错误。因为我无法继续前进。感谢。
使用--trace输出

看起来你正在使用Rails 4.2.0.beta4。 ActiveRecord将需要arel gem。将'arel'添加到您的Gemfile中。
gem 'arel', '6.0.0.beta2'
然后运行：bundle update arel
然后bundle install

Inbetween rails版本bug。更新你的rails gem，在你的项目中更改它的版本，删除Gemfile.lock并进行bundle install，这对我有用。 在这里找到它：https://medium.com/@bitadj/rake-db-migrate-fails-on-rails-v-4-2-0-betax-36ceae38da44
