ArgumentError ( is not a recognized storage provider):

我已经确定我有Carrierwave和Fog的最新宝石.这是在我的Gemfile中：

gem 'carrierwave'
gem 'aws-sdk'
gem 'fog'

fog.rb看起来像：

CarrierWave.configure do |config|
    config.fog_credentials = {
        :provider              => 'AWS',:aws_access_key_id     => 'MYACCESSKEY',:aws_secret_access_key => 'MYSECRETKACCESSKEY',:region                => 'us-east-1'
    }

    config.fog_directory = 'andrunix'
    config.fog_public    = true
    config.fog_attributes = {'Cache-Control'=>'max-age=315576000'}

结束

Uploader类看起来像：

class SalonImageUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :fog

  def store_dir
    # "andrunix" is the bucket name on S3

    "andrunix/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
  end
end

如果我将存储更改回’file’,它可以正常工作.将存储设置为“雾”会生成此错误.
