Paperclip::Error，处理缩略图时出错

Question

我正在使用回形针、imagemagick、rmagick 将图像上传到 s3。以前，图片上传功能在 ruby 1.9.3、'rails', '3.2.11' 上运行良好。升级 ruby 2.0.0 和 'rails', '4.0.3' 后出现错误。

在store.rb

#paperclip
has_attached_file :logo,
styles: {
  thumb: ["40x40#", :png],
  small: ["400x400>", :png],
  masked_with_overlay: ["288x64", :png],
  masked_with_nearby_overlay: ["238x47#", :png],
  masked_with_rewards_overlay: ["288x64", :png],
  masked_with_overlay_for_old: ["288x64", :png],
  masked_with_nearby_overlay_for_old: ["238x47#", :png],
  masked_with_rewards_overlay_for_old: ["288x64", :png],
  masked_full_card_image: ["576x128", :png],
  masked_logo_only: ["576x128", :png]
},
convert_options: { masked_with_overlay: Proc.new{self.apply_mask_and_overlay},
  masked_with_nearby_overlay: Proc.new{self.apply_mask_and_nearby_overlay},
  masked_with_rewards_overlay: Proc.new{self.apply_mask_and_rewards_overlay},
  masked_with_overlay_for_old: Proc.new{self.apply_mask_and_overlay_for_old},
  masked_with_rewards_overlay_for_old: Proc.new{self.apply_mask_and_rewards_overlay_for_old},
  masked_full_card_image: Proc.new{self.apply_mask_full_card_image},
  masked_logo_only: Proc.new{self.apply_mask_logo_only}

},
storage: :s3,
s3_credentials: "#{Rails.root}/config/s3.yml",
path: "/store_logos/:style/:id/:filename"

validates_attachment :logo, content_type: { content_type: ["image/jpg", "image/jpeg", "image/png", "image/JPG", "image/JPEG", "image/PNG"] }

这里是 Gemfile

        params[:store].delete :ms
      end
    end
  end

   render action: "edit"

这里是log

有什么帮助吗？提前致谢

Answer 1

查看日志 (:bucket_name=>"punchme-co-dev",:key=>"store_logos/masked_with_rewards_overlay/96/Casablanca.png") AWS::S3::Errors::NoSuchKey 没有这样的键) AWS 访问密钥正在使用您的图像文件路径。

Answer 2

我终于找到了解决办法。

convert: no decode delegate for this image format `/home/likewise-open/ANNETSITE/1820/RailsWorkspace/Punchme_web_Test' @ error/constitute.c/ReadImage/532.
convert: unable to open image `Builds/app/assets/images/card_overLay.png':  @ error/blob.c/OpenBlob/2587.

通过将项目文件夹 Project_web_Test Builds 重命名为 Project_web_Test_Builds，当您处理图像时 space 是不允许的。
