如何将我的 whenever 任务安装为 cron 作业?

Question

我正在使用Rails 5。 我想定期运行一个任务，所以我正在阅读有关"无论何时"宝石的信息。 安装后，我创建了文件 ./config/schedule.rb

set :environment, "development"
every 10.minutes
rake "events:calc_index"
end

不幸的是，当我尝试使用"每当 --crontab"在我的系统中安装它时，正如我被告知必须的那样，我收到此错误

localhost:cindex davea$ whenever --update-crontab

安装我的 cron 作业的正确方法是什么？

快速浏览一下文档，似乎您需要执行以下操作：every 10.minutes do，而不是every 10.minutes。
