在运行rake db:create命令时出现错误：class `Singleton'没有`extend_object'方法。

ruby-on-railsruby

当我在我的项目上运行 rake db:create 时，我会得到这个错误：
NameError: undefined method `extend_object' for class `Singleton'
Did you mean?  extended

这个项目以前在 Ruby 3.0.0 上运行，但因为出现了一些崩溃和其他问题，我现在要将其降级至 2.7.1。完整的回溯信息如下：

rake aborted!

有什么想法是怎么回事？

rake db:migrate 失败了，但是 rails s 看起来是可以工作的（直到它尝试对数据库执行任何操作并抛出 ActiveRecord::NoDatabaseError，这是预期的）。

如果我删除 Bootsnap，则错误为：

NameError: undefined method `extend_object' for class `Singleton'

我遇到了这个非常令人沮丧的问题很长一段时间，我认为它归结于一些宝石不兼容的问题。我通过以下方式修复了它：

rm Gemfile.lock 
bundle install
