我正在尝试允许对我的应用进行裁剪。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 中有问题的代码如下所示：

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 的路线是这样的：Paperclip.options[:command_path] = "/usr/local/bin/"我已经验证它确实是 ImageMagick 的家。

有趣的是，我可以毫无问题地上传图片。只是当我尝试运行此方法以裁剪它们时，我遇到了问题。有什么建议么。使用回形针 (2.3.11)

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
