Unable to start rails server with -d switch

Question

I am trying to start rails server as a daemon using the -d switch. I have installed thin server and working on Ubuntu. If it is started as a normal process, it works, but when using the -d switch, it complains of a server pid file /tmp/pids/server.pid

Even if I delete the file and try to start the server with -d switch, it won't start. Please help.

The error says:

/usr/lib/ruby/gems/1.9.1/gems/bundler-1.3.5/lib/bundler/runtime.rb:33:in `block in setup': You have already activated daemons 1.1.9, but your Gemfile requires daemons 1.1.8. Using bundle exec may solve this. (Gem::LoadError)

run the server using 'bundle exec' in the start like:

bundle exec rails s -d

Alternatively, your exception trace is stating a mismatch for the activated daemons gem. To fix this, set the version of daemons gem to be greater than (instead of equal to) 1.1.8 and try.
