Rails 6 和操作邮箱设置

Question

I've recently upgraded to ruby 2.6.0p0 and rails 6.0.2.1 . And previously I had ruby 2.3 and rails 5.2 .

When I open up existing apps and just bundle update and then rails s everything is working just fine:

=> 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

But when I try to implement the new action mailbox feature by entering this initially rails action_mailbox:install it returns the following error, this same error occurs if I enter this rails action_text:install .

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

Any ideas why this is happening?

Answer 1

If that task can't be found, then it's generally one of two things:

1. Your terminal is using a different version of rails when you run the script (maybe try bundle exec rails action_mailbox:install ?)
2. Some pieces were missed during the Upgrade Task that aren't requiring the new action mailbox tasks.

Answer 2

I had the same issue. Be sure, you require action_mailbox/engine in application.rb

require 'action_mailbox/engine'
