我正在使用whenevergem 执行每日发送电子邮件的任务。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，它起作用了！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，我收到一个错误
hihi rake 中止了！连接被拒绝 - 连接(2)
我跟踪时的错误
rake coffee RAILS_ENV=production --trace
** Invoke coffee (first_time)

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起作用了。请帮助我，谢谢！
