Delayed Job suddenly not starting in production
We had a client server not want to start up Delayed Job on their server using the script/delayed_job command.
The culprit? DelayedJob no longer requires deamons as a runtime dependency with this commit
Which gives you an error like this:
$ ruby script/delayed_job -i 0 start /data/app/shared/bundled_gems/ruby/1.9.1/gems/delayed_job-3.0.0/lib/delayed/command.rb:4:in `rescue in': You need to add gem 'daemons' to your Gemfile if you wish to use it. (RuntimeError) from /data/app/shared/bundled_gems/ruby/1.9.1/gems/delayed_job-3.0.0/lib/delayed/command.rb:1:in ` ' from /data/app/shared/bundled_gems/ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `require' from /data/app/shared/bundled_gems/ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `block in require' from /data/app/shared/bundled_gems/ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:236:in `load_dependency' from /data/app/shared/bundled_gems/ruby/1.9.1/gems/activesupport-3.2.1/lib/active_support/dependencies.rb:251:in `require' from /data/app/current/script/delayed_job:4:in ` '
The fix is simple, add:
gem "daemons"
To your Gemfile, bundle install and redeploy.
Enjoy.
