Capistrano - Carrierwave LoadError: cannot load such file -- carrierwave/processing/mime_types

Question

When I run cap production deploy I keep running into this error with carrier wave. I have posted my carrierwave settings below.

Tasks: TOP => deploy:assets:precompile
The deploy has failed with an error: Exception while executing as [email protected]: rake exit status: 1
rake stdout: Nothing written
rake stderr: rake aborted!

Carrierwave.rb

if Rails.env.production? || Rails.env.staging?
  CarrierWave.configure do |config|
    config.fog_credentials = {
        provider:                   'AWS',
        aws_access_key_id:         Rails.application.secrets.AWS_ACCESS_KEY_ID,
        aws_secret_access_key:     Rails.application.secrets.AWS_SECRET_ACCESS_KEY,
        region:                    Settings.aws_region
    }
    config.fog_directory = Settings.aws_s3_bucket_name
    config.permissions = 0666
    config.directory_permissions = 0777
    config.storage = :fog
  end
end

CarrierWave::SanitizedFile.sanitize_regexp = /[^[:word:]\.\-\+]/

My secrets.yml has the AWS keys defined - I had run into missing aws keys and solved that issue with secrets.yml symlinked in my deploy.rb file. I'm using carrierwave 1.0.0 in my Gemfile.

mime_types file has been removed from carrierwave, see commit.

You do likely have require 'carrierwave/processing/mime_types' on the top of app/uploaders/author_image_uploader.rb. You need to either remove carrierwave mime_types references from the project and switch to mime-types gem which is a runtime dependency of carrierwave now or rollback to the previous carrierwave version.
