NoMethodError 'crop' in uploader

[ghost]

Hi,
I have an error on rails 4.2 using the gem carrierwave-crop 0.1.2.
when I try to crop the image an error occurs:

NoMethodError (undefined method `crop' for #LocationShowcaseUploader::Uploader70164076328740:0x007fa0b6842a98)

my code:

class LocationShowcase < ActiveRecord::Base
  # other stuff..

  mount_uploader :image, LocationShowcaseUploader, mount_on: :image_file_name
  crop_uploaded :image

  # other stuff..
end

class LocationShowcaseUploader < CarrierWave::Uploader::Base
  include CarrierWave::Compatibility::Paperclip
  include SharedUploader
  include CarrierWave::MiniMagick
  include CarrierWave::ImageOptimizer

  # other stuff..

  version :default do
    process resize_to_fit: [600, -1], optimize: [{ quality: 60 }]
  end

  version :large, if: :is_cropped? do
    process crop: :default
    process resize_to_fit: [1335, -1], optimize: [{ quality: 60 }]
  end

  version :medium, if: :is_cropped? do
    process crop: :default
    process resize_to_fit: [770, -1], optimize: [{ quality: 60 }]
  end

  version :small, if: :is_cropped? do
    process crop: :default
    process resize_to_fit: [610, -1], optimize: [{ quality: 60 }]
  end

  version :admin, if: :is_cropped? do
    process crop: :default
    process resize_to_fit: [-1, 70], optimize: [{ quality: 60 }]
  end

  private

  def is_cropped?(image)
    model.image_crop_x.present?
  end

end

Maybe too late to the party but I had the same problem. Noticed had gem "carrierwave-crop" before gem "carrierwave" inside my Gemfile. Changed the order, did bundle install and the error disappeared.
