在heroku上使用rapns进行推送通知 [英] Using rapns on heroku for push notification

问题描述

我在我的Rails应用上使用了gem rapns（https://github.com/ileitch/rapns）。根据rapns文档，我需要运行

bundle exec rapns $ b

/ b>

启动守护进程，该进程会检查数据库以发送新通知。

<所以我做了以下事情：

heroku run bundle exec rapns production --foreground

给了我一个错误：

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

我对rails和ruby非常新颖，有人能告诉我发生了什么问题吗？
 
 
I'm using gem rapns (https://github.com/ileitch/rapns) on my rails app. 

According to rapns doc, I need to run 

  
bundle exec rapns
to kick start the daemon process which checks database for new notifications to send.

So I did following:

  
heroku run bundle exec rapns production --foreground
which gave me error:
Running bundle exec rapns production --foreground attached to terminal... up, run.3

from /app/.bundle/gems/ruby/1.9.1/bin/rapns:19:inload'
from /app/.bundle/gems/ruby/1.9.1/bin/rapns:19:in `'
I'm very very new to rails and ruby, can someone tell me what's going wrong?
解决方案
You need to remove the pid_file option from the production configuration and/or upgrade to 1.0.2, which is tolerant of a non-writable pid_file option.
