我正在使用ruby 2.6.3、Rails 6.0.2.2和Postgres 12开发一个Ruby应用程序。

在我使用迁移向表添加索引之前，一切都运行得很好：

代码语言：javascript
复制
class AddIndexToUserEmail < ActiveRecord::Migration[6.0]
  def change
    add_index :users, :email, unique: true
  end
end

运行rails test:models返回以下无限转储，我无法摆脱。

任何帮助我们都将不胜感激。

代码语言：javascript
复制
% rails test:models
Run options: --seed 62890

此问题是由于最新的最小版本(5.14)造成的。他们在rails中有fixed，但是补丁还没有发布

打开你的gemfile并明确设置你的最小版本：

代码语言：javascript
复制
gem 'minitest', '<=5.13'

然后运行bundle update minitest。然后，它将在错误消息中向您显示数据库的真正问题。
