我目前正在将一个 Rails 项目从 v5.2.3 升级到 v6.0。我正在关注 guide升级 rails 。但我只停留在第一步。一旦我更改了 gemfile 中的 rails 版本并更新了 rails 就没有任何效果。运行 rails server 给我这个错误 uninitialized constant ActiveRecord::ConnectionAdapters::ConnectionManagement (NameError)

以下是完整的堆栈跟踪:

最佳答案

我遇到了同样的问题。我修复了它升级 airbrake gem

gem 'airbrake', '~> 10.0.3'
