cannot load such file -- fog (LoadError) #401

guilpejon · 2017-10-07T03:37:54Z

I have an application working with fog, carrierwave and AWS, and then I decided to switch to fog-aws.

All I did was change gem 'fog' to gem 'fog-aws' in my Gemfile, and I thought it would work right away, but now the server won't start.

The error seems to be happening inside my config.fog_credentials code in my carrierwave initialization file.

I tried adding require 'fog/aws' but it didn't worked, and it returns false when I try to do this require on the console as well, even though I can run this line Fog::Storage.new(provider: 'AWS', aws_access_key_id: 'aws_id', region: 'us-west-2', aws_secret_access_key: 'aws_secret') without a problem.

Am I doing something wrong?

Here is my carrierwave initialization file:

CarrierWave.configure do |config|
  if Rails.env.test?
    config.storage :file
    config.asset_host = 'http://localhost:3000'
  else
    config.fog_credentials = {
      provider:               ENV['FOG_PROVIDER'],
      aws_access_key_id:      ENV['AWS_ACCESS_KEY_ID'],
      aws_secret_access_key:  ENV['AWS_SECRET_ACCESS_KEY'],
      path_style:             ENV['FOG_PATH_STYLE']
    }
    config.storage = :fog
    config.fog_use_ssl_for_aws = true
    config.fog_directory  = ENV['FOG_DIRECTORY']
    config.fog_public     = true
    config.fog_attributes = { 'Cache-Control': 'max-age=315576000' }
    config.asset_host = 'https://s3.amazonaws.com/website'
  end
end

And here is the dump:

That appears to be a somewhat older version of carrierwave, could you try updating to see if that solves the issue?

guilpejon · 2017-10-17T22:01:36Z

Wasn't expecting this to work, but it did! I was using version 1.1.0 of carrierwave, and after updating it to 1.2.1 my code worked. Thanks @geemus

geemus · 2017-10-18T14:47:32Z

@guilpejon awesome, honestly I wasn't sure either, but thought it was worth a try before we dug in. Thanks for the update!

lpradovera · 2017-10-26T14:43:20Z

We are seeing the same problem with Carrierwave 1.2.1 - @guilpejon , what was the change you did exactly? Thanks!

guilpejon · 2017-10-26T16:25:01Z

@lpradovera In my case I just updated Carrierwave to version 1.2.1 and I was able to start the server, but unfortunately I realized afterwards that fog-aws was still not working properly, so I returned to fog since I couldn't spend any more time debugging it. I will start a new issue here about it when I get the chance, and I suggest you to do the same.

CarrierWave.configure do |config|
  if Rails.env.test?
    config.storage :file
    config.asset_host = 'http://localhost:3000'
  else
    config.storage = :fog
    config.fog_use_ssl_for_aws = true
    config.fog_directory  = ENV['FOG_DIRECTORY']
    config.fog_public     = true
    config.fog_attributes = { 'Cache-Control': 'max-age=315576000' }
    config.asset_host = 'https://s3.amazonaws.com/website'

    config.fog_credentials = {
      provider:               ENV['FOG_PROVIDER'],
      aws_access_key_id:      ENV['AWS_ACCESS_KEY_ID'],
      aws_secret_access_key:  ENV['AWS_SECRET_ACCESS_KEY'],
      path_style:             ENV['FOG_PATH_STYLE']
    }
  end
end

Your carrierwave.rb file needs to look like this. Your app needs to know that config.storage is == :fog before it gets to fog_credentials

petrbela · 2018-01-10T18:54:59Z

In our case, fog_provider had to be configured before fog_credentials. Thanks @cameronbass for the tip!

archfish · 2018-06-11T09:36:31Z

just copy lib/fog-aws.rb to lib/fog.rb fix this
@lpradovera @guilpejon

CarrierWave.configure do |config|
  config.storage = Fog
  config.fog_directory  = 'mybucket'
  config.fog_public     = false
  config.fog_attributes = {'Cache-Control' => 'max-age=315576000'}

  config.fog_credentials = {
    provider:                'AWS',
    aws_access_key_id:       'access_key',
    aws_secret_access_key:   'secret_key',
    aws_signature_version:   2,
    endpoint:                'http://my.domain:7480',
    path_style:              true,
    region:                  'us-east-1'
  }
end

config.fog_provider = 'fog/aws'
