兼容性问题？ rake db:migrate - 参数数量错误（1 代表 0）

Posted 2023-02-23

【中文标题】兼容性问题？ rake db:migrate - 参数数量错误（1 代表 0）

【英文标题】：Compatibility issue? rake db:migrate - wrong number of arguments (1 for 0)

【发布时间】：2015-01-25 04:48:08

【问题描述】：

我正在尝试运行一个简单的迁移，但出现此错误。我认为这是某种兼容性错误。我该如何修复它以及如何避免将来出现兼容性问题？

【问题讨论】：

Can't migrate database after scaffold. Section 2.2 Ruby on Rails Tutorial Michael Hartl. 的可能重复项

我没有使用脚手架

请仔细阅读链接，这是一个rails错误，我今天强制关闭3个这样的问题。

谢谢。我很困惑。我什至没有“arel”宝石。

【参考方案1】：

答案在这里：Can't migrate database after scaffold. Section 2.2 Ruby on Rails Tutorial Michael Hartl

您需要按照那里的说明安装 arel gem。
