问题


I have tried several solution given on stackoverflow and github, but couldnt find the solution. I am using carrierwave (0.10.0) and fog-aws (0.8.1) gems for my app to upload image to S3.

NameError: uninitialized constant CarrierWave::Storage::Fog

And when i tried using the fog(1.37.0) gem instead of the fog-aws gem, then i am getting the different error.

回答1:


Update your gemfile from gem "fog-aws" to gem 'fog', require: 'fog/aws'.




回答2:


Make sure your configure file(carrierwave.rb) is in initializers folder.




回答3:


Have you included the "fog-aws" gem? I feel like I had a similar error for not following this section of the documentation: https://github.com/carrierwaveuploader/carrierwave#using-amazon-s3




回答4:


Fixed the issue by adding Fog gem in my Gemfile

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

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



回答5:


For me this was fixed by moving the config.storage = :fog after the config.fog_credentials = ... line in the Carrierwave initializer.
