我搜索了上述问题，并得到了这个，但这并不能帮助我。无论我只发现了这个解决方案。是否跨越这个问题的任何人来之前，如果是你做了什么来解决呢？任何帮助将AP preciated。谢谢
I searched for the above issue and got this , but this doesn't helped me out. Everywhere I found this solution only.Does any one came across this issue before, if yes what you did to tackle it? Any help on this will be appreciated. Thanks
推荐答案
我只是有我的想法是一样的问题，我更新了我的宝石，并翻掉分贝，后来我有一个非常类似的消息，然后我创建了一个新的Rails应用程序只是为了比较和事实证明迁移文件已被修改，现在包括调用方法的列代替。
I just had what I think is the same issue, I updated my gem, and dropped my db, later I got a very similar message, then I created a new rails app just to compare and it turns out the migration file has been changed, now it includes the columns instead of calling methods.
我希望它能帮助。
