在 heroku 上使用 rapns 进行推送通知
我在我的 Rails 应用程序上使用 gem rapns (https://github.com/ileitch/rapns)。
根据 rapns 文档，我需要运行
捆绑执行 rapns
启动守护进程进程，该进程检查数据库以查找要发送的新通知。
所以我做了以下事情：
heroku run bundle exec rapns production --foreground
这给了我错误：
Running bundle exec rapns production --foreground attached to terminal... up, run.3

from /app/.bundle/gems/ruby/1.9.1/bin/rapns:19:in `'
我对 Rails 和 ruby 非常陌生，有人可以告诉我出了什么问题吗？
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:in `'
I'm very very new to rails and ruby, can someone tell me what's going wrong?

您需要从生产配置中删除 pid_file 选项和/或升级到 1.0.2，它可以容忍不可写的 pid_file 选项。
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.
