NameError: uninitialized constant LogStasher::ActiveRecord

[bastoune]

I added the gemfile and the logstaher.yml file (also tried with the lined in application.rb) as specified
But I got this error from unicorn

==> /home/mushin-api/unicorn/log/unicorn.stdout.log <==
bundler: failed to load command: unicorn (/home/mushin-api/mushin-api/source/vendor/bundle/ruby/2.3.0/bin/unicorn)

Sounds like you have ActiveRecord logging enabled, but don't have ActiveRecord installed. Are you using ActiveRecord? If not, set config.logstasher.record_enabled = false.
