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",

只需删除您的gemfile版本。也许对你有帮助。

    gem "paperclip",'4.3.6' #last stable version
    gem 'aws-sdk', '< 2.0'

than bundle install
