系统：Windows 10 使用：Ruby的当前版本 我试图按照https://github.com/piedoom/tumbot
上的说明来运行tumbot但是，尽管安装了捆绑软件，它还是拒绝迁移。我得到的错误是 https://66.media.tumblr.com/029bbd52eda91c2ffbac01f7c8af467d/27d62997ece87db2-48/s540x810/4c5b63b9acfbd7495342cb667fc8c78236964d60.png

反正有解决此问题的方法吗？
答案 0 :(得分：3)
我遇到了相同的错误，并按以下方式修复： https://github.com/padrino/padrino-framework/blob/master/padrino-gen/lib/padrino-gen/padrino-tasks/activerecord.rb#L131-L137
ActiveRecord::Migrator.migrate似乎已过时。
