ImageMagick和回形針沒有找到我的文件在S3（Jcrop）上的位置

Question

我想允許在我的應用上裁剪。然而，當我運行這個方法：

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 /Users/skline/.rvm/gems/ruby-1.9.2-p180@nutra/gems/railties-3.0.7/lib/rails/commands.rb:23:in `<top (required)>' 
    from script/rails:6:in `require' 
    from script/rails:6:in `<main>' 

在回形針段出錯的代碼如下所示：

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 

我的化身模型是這樣的：

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" 

而且我給Paperclip在我的development.rb中找到ImageMagick的路線是這樣的：Paperclip.options[:command_path] = "/usr/local/bin/"我已經證實這確實是ImageMagick的家園。

有趣的是，我可以上傳圖像沒有任何問題。簡單地說，當我試圖運行這個方法來裁剪它們時，我遇到了問題。有什麼建議麼。使用回形針（2.3.11）

這適用於S3和當地

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
