如何解决cron工作难题？

问题描述

我在lib / tasks的rails项目中创建cron作业

namespace :job do
 desc "TODO"
 task finish_job: :environment do
 jobs = Job.where(end_date:Date.today())
  if jobs != []
    print('Found jobs!')
    
  for job in jobs
        promoter_ids_in_promoter_requests = job.promoters_requests_jobs.where(status: "accept").pluck(:promoter_id)
        
        promoters = Promoter.where(id:promoters).update_all(is_enrolled: false)
    end
else
    print("No jobs!")
end
end 

end

当我运行此命令bundle exec whenever --update-crontab时 我收到此错误

这些不是错误，而是弃用警告。 如果命令失败，请张贴所有错误代码。
