Looks like you're stuck with a very old version of ruby. Please provide more information about the system:

• OS
• Ruby version

Hi, I have ruby 1.8.7 version. When I gave daemon with server option .. its not working. I am new to ruby language. When I saw the code I did not find any code which used 'daemon' gem. Could you please explain which part of the code makes the application daemon?

I am not finding any code which says 'Daemons.daemonize(...)'

Ruby 1.8.7 is way too old, it was retired three years ago. Please upgrade your Ruby and see if it helps.

Hi,

It works with Ruby 1.8.7, but you will have to remove daemon 1.2.3, see below:

redis-stat

/usr/lib/ruby/site_ruby/1.8/rubygems.rb:233:in activate': can't activate daemons (~> 1.1.9, runtime) for ["redis-stat-0.4.13"], already activated daemons-1.2.3 for ["thin-1.5.1", "redis-stat-0.4.13"] (Gem::LoadError) from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:249:inactivate' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:248:in each' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:248:inactivate' from /usr/lib/ruby/site_ruby/1.8/rubygems.rb:1082:in `gem' from /usr/bin/redis-stat:18

gem list|grep daemon

daemons (1.2.3, 1.1.9)

gem uninstall daemons --version 1.2.3

Successfully uninstalled daemons-1.2.3
