ruby-on-rails - Rails 6 和操作邮箱设置

Question

我最近升级到了ruby 2.6.0p0 和rails 6.0.2.1。之前我有ruby 2.3和rails 5.2。

当我打开现有应用程序并捆绑更新，然后rails 时，一切都工作正常:

=> Booting Puma
=> Rails 6.0.2.1 application starting in development 
=> Run `rails server --help` for more startup options
Puma starting in single mode...
* Version 3.12.0 (ruby 2.6.0-p0), codename: Llamas in Pajamas
* Min threads: 5, max threads: 5
* Environment: development

但是当我尝试实现新的 action mailbox 时通过最初输入此 rails action_mailbox:install 功能，它会返回以下错误，如果我输入此 rails action_text:install，也会发生相同的错误。

rails aborted!
Don't know how to build task 'action_mailbox:install' (See the list of available tasks with `rails --tasks`)

有什么想法为什么会发生这种情况吗？

我也遇到了同样的问题。确保您在 application.rb

中需要 action_mailbox/engine

require 'action_mailbox/engine'
