Ruby on rails NameError:未初始化的常量CarrierWave:：Storage:：Fog

我在stackoverflow和github上尝试了几种解决方案，但都没有找到解决方案。我正在使用carrierwave（0.10.0）和fog aws（0.8.1）gems将我的应用程序的图像上传到S3

您是否包含了“fog aws”宝石？我觉得我有一个类似的错误，因为我没有遵循文档的这一部分：

将您的gem文件从gem“fog aws”更新到gem“fog”，要求：'fog/aws'

通过在我的gem文件中添加fog gem修复了这个问题

gem 'fog', require: 'fog/aws'

如所述，从lib/carrierwave/storage/fog.rb中删除了配置文件，并将carrierwave配置置于config/initializer中

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => 'XYZ',
    :aws_secret_access_key  => 'ABC',
    :region                 => 'region'
  }
  config.fog_directory  = 'bucket_name'
end
