当我尝试使用 fog(1.37.0)宝石而不是 fog-aws 宝石时，我得到了不同的错误.
And when i tried using the fog(1.37.0) gem instead of the fog-aws gem, then i am getting the different error.

推荐答案
通过在我的Gemfile中添加雾宝石来解决此问题
Fixed the issue by adding Fog gem in my Gemfile
gem 'fog', require: 'fog/aws'
如 lib/carrierwave/storage/fog.rb 中删除了配置文件.rel ="nofollow">起雾的宝石，并将载波配置放在 config/initializers/carrierwave.rb
Removed the configuration file from lib/carrierwave/storage/fog.rb as mentioned for fog-aws gem and placed the carrierwave configuration in config/initializers/carrierwave.rb
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
