リスト内のArgumentError＃index（必須ではない：バケツオプション）

Question

リスト内のArgumentError＃index（必須ではないバケットオプション） 私は何が必要かわかりません。私はペーパークリップ付きのs3を入れる過程にあります。私のエラーは6行目から来ています。私がそれを削除すれば、エラーは発生しません。

index.html.erb

<div class="center"> 
<div class="row"> 
    <% @listings.each do |listing| %> 
<div class="col-md-3"> 
    <div class="thumbnail"> 
    <%= image_tag listing.image.url %> 
    <div class="caption"> 
     <h3><%= listing.name %></h3> 
     <p><%= number_to_currency(listing.price) %></p> 
     <%= link_to 'Show', listing, class: "btn btn-link" %> 
     <%= link_to 'Edit', edit_listing_path(listing), class: "btn btn-link" %> 
     <%= link_to 'Destroy', listing, method: :delete, data: { confirm: 'Are you sure?' }, class: "btn btn-link" %> 
     </div> 
     </div> 
    </div> 
    <% end %> 
</div> 

<br> 

<%= link_to "New Listing", new_listing_path, class: "btn btn-link" %> 

モデル/ listings.rb

    has_attached_file :image, :styles => { :medium => "200x", :thumb => "100x100>" }, :default_url => "default.jpg" 
    validates_attachment_content_type :image, :content_type => /\Aimage\/.*\Z/

ペーパークリップgithubのwikiによれば、bucket構成がpaperclip_defaultsないためであるべきですs3 credentials。 like：

config.paperclip_defaults = { 
    storage: :s3, 
    s3_host_name: "s3_us-east-1.amazonaws.com", 
    bucket: ENV['AWS_BUCKET'], 
    s3_credentials: { 
    access_key_id: ENV['AWS_ACCESS_KEY_ID'], 
    secret_access_key: ENV['WS_SECRET_ACCESS_KEY'], 
    s3_region: ENV['AWS_REGION'], # or ENV['AWS_REGION'] 
    } 
}
