Using rapns on heroku for push notification

问题:

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?

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.
