Question

I have gone through different posts but got no help, I am trying to upload my images to Amazon S3 I double checked my asw credentials they all are correct, here are the required files please help

Gemfile

gem 'aws-sdk', '< 2.0'
gem 'devise'
gem "paperclip", "~> 5.0.0.beta1"
gem 'bootstrap-sass', '~> 3.3.6'
gem 'bootstrap-material-design'
gem 'nested_scaffold'  

config/environments/development.rb

  # Raises error for missing translations
  # config.action_view.raise_on_missing_translations = true
  config.action_mailer.default_url_options = { host: 'localhost', port: 3000 }
  config.action_mailer.delivery_method = :smtp

  config.paperclip_defaults = {
  storage: :s3,
  s3_credentials: {
    bucket: "bucketName",
    access_key_id: "xoxoxo",
    secret_access_key: "secret_key"

  }
}

config/initializers/paperclip.rb

# config/initializers/paperclip.rb
Paperclip::Attachment.default_options[:url] = ':s3_domain_url'
Paperclip::Attachment.default_options[:path] = '/:class/:attachment/:id_partition/:style/:filename'
Paperclip::Attachment.default_options[:s3_host_name] = 's3-us-west-2.amazonaws.com'

And while uploading Iam still getting the error

NameError in CorporateTrainersController#create uninitialized constant Paperclip::Storage::S3::Aws

Extracted source (around line #29):          
  # POST /corporate_trainers.json
  def create
    @corporate_trainer = CorporateTrainer.new(corporate_trainer_params)
