Ruby on rails 在heroku上使用RAPN进行推送通知

我用的是宝石环(https://github.com/ileitch/rapns)在我的rails应用程序上

根据rapns医生的说法，我需要跑步

bundle-exec-rapns

启动守护进程，该进程检查数据库中是否有要发送的新通知

所以我做了以下几点：

heroku run bundle exec rapns产品——前景

这给了我一个错误：

Running bundle exec rapns production --foreground attached to terminal... up, run.3

我对rails和ruby非常陌生，有人能告诉我出了什么问题吗？

您需要从生产配置中删除pid_文件选项和/或升级到1.0.2，它允许使用不可写的pid_文件选项
