Heroku上的Rails 4中的回形针NameError（未初始化的常量AWS :: S3 :: Errors）

Question

When I upload an image using paperclip and s3 storage. The app works fine locally, I've made the required changes to use s3 for heroku , but on heroku the issue remains continues:

Gemfile

ruby '2.0.0'
gem 'rails', '4.0.3'
gem 'aws-s3'
gem 'aws-sdk', '< 2.0'
gem 'paperclip', "~> 3.5.3"

store.rb

class Store < ActiveRecord::Base
  has_attached_file :logo,
  styles: {
  thumb: ["40x40#", :png],
  small: ["400x400>", :png]},
  default_url: "#{Rails.root}/app/assets/images/missing.jpg",
  storage: :s3,
  s3_credentials: "#{Rails.root}/config/s3.yml",
  path: "/store_logos/:style/:id/:filename"
end

config/s3.yml

development:
  bucket: app-dev
  access_key_id: ***********
  secret_access_key: ***************
production:
  bucket: app-pro
  access_key_id: ***********
  secret_access_key: ***************

  require 'aws-sdk-v1'
  require 'aws-sdk'
  has_attached_file :logo,
  styles: {
