好的，经过一段漫长的旅程，我找到了解决方案。我没有安装

imagemagick

。 我刚下载了

gem 'carrierwave', github: 'carrierwaveuploader/carrierwave'
gem "fog-aws"
gem 'mini_magick'

这三颗宝石。请使用下载

imagemagick

sudo apt-get -y install imagemagick

在使用

Minimagick

开始工作之前

class S3uploaderUploader < CarrierWave::Uploader::Base
  include CarrierWave::MiniMagick      
  storage :fog

  def store_dir
    "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
  def cache_dir
    '/tmp/cache/s3file'
  end
  def extension_white_list
    %w(jpg jpeg png gif)
  end
  #version1
  version :detailVertical do
    process :quality => 50
  end
  #version2
  version :detailHorizontal do
    process :quality => 50
  end
  #version3
  version :mainVertical, :from_version => :detailVertical do
    process :resize_to_fit => [240, 320]
    process :quality => 100
  end
  #version4
  version :mainHorizontal, :from_version => :detailHorizontal do
    process :resize_to_fit => [240, 180]
    process :quality => 100
  end
end

module CarrierWave
  module MiniMagick
    def quality(percentage)
      manipulate! do |img|
        img.quality(percentage.to_s)
        img = yield(img) if block_given?
        img
      end
    end
  end
end
