ImageMagick和Paperclip在S3Jcrop上找不到我的文件的位置

问题描述

| 我正在尝试允许在我的应用程序上裁剪。但是，当我运行此方法时：

  def avatar_geometry(style = :original)
    @geometry ||= {}
    @geometry[style] ||= Paperclip::Geometry.from_file avatar.path(style)
  end


identify: unable to open image `/original/4/nutra.jpg\': No such file or directory @ error/blob.c/OpenBlob/2587.
Paperclip::NotIdentifiedByImageMagickerror: /original/4/nutra.jpg is not recognized by the \'identify\' command.
    from /Users/skline/.rvm/gems/ruby-1.9.2-p180@nutra/gems/paperclip-cloudfiles-2.3.10.1/lib/paperclip/geometry.rb:26:in `from_file\'
    from /Users/skline/NutraNation1/app/models/user.rb:111:in `avatar_geometry\'
    from (irb):2
    from /Users/skline/.rvm/gems/ruby-1.9.2-p180@nutra/gems/railties-3.0.7/lib/rails/commands/console.rb:44:in `start\'
    from /Users/skline/.rvm/gems/ruby-1.9.2-p180@nutra/gems/railties-3.0.7/lib/rails/commands/console.rb:8:in `start\'

    from script/rails:6:in `require\'
    from script/rails:6:in `<main>\'

Paperclip中令人反感的代码如下：

def self.from_file file
      file = file.path if file.respond_to? \"path\"
      geometry = begin
                   Paperclip.run(\"identify\",\"-format %wx%h :file\",:file => \"#{file}[0]\")
                 rescue Cocaine::ExitStatusError
                   \"\"
                 rescue Cocaine::CommandNotFoundError => e
                   raise Paperclip::CommandNotFoundError.new(\"Could not run the `identify` command. Please install ImageMagick.\")
                 end
      parse(geometry) ||
        raise(NotIdentifiedByImageMagickerror.new(\"#{file} is not recognized by the \'identify\' command.\"))
    end

我的头像模型如下所示：

AVATAR_SW = 55
  AVATAR_SH = 55
  AVATAR_NW = 240
  AVATAR_NH = 240

  has_attached_file :avatar,:styles => { :normal => [\"#{AVATAR_NW}x#{AVATAR_NH}>\",:jpg],:small => [\"#{AVATAR_SW}x#{AVATAR_SH}#\",:jpg] },:storage => :s3,:s3_credentials => \"#{RAILS_ROOT}/config/s3.yml\",:path => \"/:style/:id/:filename\"

我给Paperclip在我的development.rb中找到ImageMagick的途径是：我已经证实的

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

确实是ImageMagick的故乡。 有趣的是，我可以毫无问题地上传图像。只是当我尝试运行此方法以裁剪它们时，我才遇到问题。有什么建议么。使用回形针（2.3.11）     

解决方法

        这适用于s3和本地

def photo_geometry(style = :original)
  @geometry ||= {}
  path = (avatar.options[:storage]==:s3) ? avatar.url(style) : avatar.path(style)
  @geometry[style] ||= Paperclip::Geometry.from_file(path)
end
