【问题描述】：
我正在使用whenever gem 执行每日发送电子邮件任务。
我在 RAKEFILE 名称咖啡中创建了一个 rake 任务。这是我的任务代码：
task :coffee => :environment do
ReservationBooksNotify.notify.deliver
puts "hihi"
end
当我在控制台中运行此任务时
rake coffee，成功了！
但是当我在 schedule.rb 中创建一个计划以每分钟自动发送邮件时，我得到一个错误
嗨嗨 耙中止！ 连接被拒绝 - connect(2)
追踪时的错误
rake coffee RAILS_ENV=production --trace
** Invoke coffee (first_time)
** Invoke environment (first_time)
** Invoke rails_admin:disable_initializer (first_time)
** Execute rails_admin:disable_initializer
[RailsAdmin] RailsAdmin initialization disabled by default. Pass SKIP_RAILS_ADMIN_INITIALIZER=false if you need it.
** Execute environment
** Execute coffee
rake aborted!
Connection refused - connect(2)

Tasks: TOP => coffee
我的 schedule.rb（在 /config 中）
set :output, "~/Working/whenever.log"
every 2.minutes do
rake 'coffee'
end
我认为我的邮件配置没有问题，因为当我在控制器和控制台中发送邮件时它可以工作。请帮助我，谢谢！
【问题讨论】：
-
您是否能够从同一台机器上的控制台发送电子邮件，即在生产环境中，还是在开发环境中。尝试在生产模式下启动控制台，然后执行
ReservationBooksNotify.notify.deliver，你可能会得到一个线索。
