Ruby on rails 4 '；缺少必需选项：bucket选项'；S3回形针导轨的开发

我按照此链接中的说明进行操作：

我收到以下错误消息：

ActionView::Template::Error (missing required :bucket option):

它指向一条线：

<%= image_tag company.profile_image.url %>

development.rb：

 Paperclip.options[:command_path] = "/usr/local/bin/"

  config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }

---

谢谢大家!

那么您是在生产环境（在heroku上）还是在开发中遇到了错误？

 Paperclip.options[:command_path] = "/usr/local/bin/"

  config.paperclip_defaults = {
  :storage => :s3,
  :s3_credentials => {
    :bucket => ENV['S3_BUCKET_NAME'],
    :access_key_id => ENV['AWS_ACCESS_KEY_ID'],
    :secret_access_key => ENV['AWS_SECRET_ACCESS_KEY']
    }
  }
