mysql - redmin安装过过程中的坑，求填。-PHP 중국어 네트워크 Q&A

1.相关环境： ubutu12.04 mysql5.5 ruby2.1 redmine3.3 gem 2.2.5
rails 4.2.6

2.redmin的配置文件配置如下：
database.yml:
production:
adapter: mysql2
database: redmine
host: 127.0.0.1
username: redmine
password: 123456
encoding: utf8

configuration.yml
default:
email_delivery:

delivery_method: :smtp
smtp_settings:
address: 127.0.0.1
port: 25
authentication: :login
#domain: localhost
user_name: 'redmin@localhost'
password: '123456'

production:
email_delivery:

delivery_method: :smtp
smtp_settings:
address: 127.0.0.1
port: 25

3.遇到的问题：
在初始化数据库，创建表使用该命令 RAILS_ENV=production rake db:migrate

出现报错：rake aborted!
NoMethodError: undefined method `address=' for ActionMailer::Base:Class

下面是详细的追踪的结果：
RAILS_ENV=production rake db:migrate --trace
** Invoke db:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
rake aborted!
NoMethodError: undefined method `address=' for ActionMailer::Base:Class
