在使用定时的时候，开发环境，可以执行通过，在本地用生产模式启动也可以通过， 但是在生产环境，跟测试环境都不能执行通过。 错误：

Run 'bin/rails runner -h' for help.

uninitialized constant Rails::Command::RunnerCommand::GrabOrderManager

schedule.rb 文件配置

rails_env = ENV['RAILS_ENV'] || :production
set :environment, rails_env
set :output, 'log/cron.log'

every :day, :at => '01:00 am' do
    runner "GrabOrderManager.statistics"
end

every :day, :at => '04:30 am' do
    runner "GrabOrderManager.dynamic_done"
end

crontab -l
