Ruby on Rails bundle exec rake assets:precompile error - no such file to load -- gelf

Question

When I run RAILS_ENV=production bundle exec rake assets:precompile I get:

Rake aborted!
no such file to load -- gelf

Tasks: TOP => environment
(See full trace by running task with --trace)
rake aborted!

if I run it with --trace I get:

** Invoke assets:precompile:all (first_time)
** Execute assets:precompile:all
** Invoke assets:precompile:primary (first_time)
** Invoke assets:environment (first_time)
** Execute assets:environment
** Invoke environment (first_time)
** Execute environment
rake aborted!

I havent been able to find any solution, or question with the same error so I'm thinking it might be something basic.

Is there anyone who has had the same problem and figured it out or knows what's going wrong?

Is there any other relevant code? Does the error point to a specific part of the app (with a line number, maybe)? — jstim
What is gelf and why does config/initializers/graylog.rb need it? — Ryan Bigg

You are missing the gelf gem, in your gemfile, resulting in the error:

no such file to load -- gelf

Simply add the following line to your gemfile:

gem 'gelf'

And run bundle install, from the root of your app.
