找不到回形针文件错误

Question

我刚刚从一个paperclip rails插件切换到一个paperclip gem.该项目是rails 2.3应用程序,我使用的是paperclip 2.7.2 gem.

我收到以下奇怪的错误:

identify: unable to open image `file': No such file or directory @ error/blob.c/OpenBlob/2617.
identify: no decode delegate for this image format `file' @ error/constitute.c/ReadImage/544.

看起来像paperclip正在寻找一个名为'file'的文件,但我不知道为什么.我没有改变以前的任何代码.它曾经工作过,我所做的只是升级到更新的版本,并在插件上使用gem.

有任何想法吗？

更新

它是纸夹中的一个错误,它不能正确解析命令的内容.我深入研究回形针来源,找到:

def run(cmd, arguments = "", local_options = {})
  if options[:image_magick_path]
    Paperclip.log("[DEPRECATION] :image_magick_path is deprecated and will be removed. Use :command_path instead")
  end
  command_path = options[:command_path] || options[:image_magick_path]
  Cocaine::CommandLine.path = [Cocaine::CommandLine.path, command_path].flatten.compact.uniq
  local_options = local_options.merge(:logger => logger) if logging? && (options[:log_command] || local_options[:log_command])

  Cocaine::CommandLine.new(cmd, arguments, local_options).run
end

和

# Uses ImageMagick to determing the dimensions of a file, passed in as either a
# File or path.
# NOTE: (race cond) Do not reassign the 'file' variable inside this method as it is likely to be
# a Tempfile object, which would be eligible for file deletion when no longer referenced.
def self.from_file file
  file_path = file.respond_to?(:path) ? file.path : file
  raise(Paperclip::NotIdentifiedByImageMagickError.new("Cannot find the geometry of a file with a blank name")) if file_path.blank?
  geometry = begin
               Paperclip.run("identify", "-format %wx%h :file", :file => "#{file_path}[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_path} is not recognized by the 'identify' command."))
end

由于某种原因,Paperclip.run命令无法替换:file占位符.我通过在命令行上运行以下内容来验证这一点:

identify :file

猴子修补替换手动产生其他类似的事情发生的错误.

Answer 1

好的,我设法解决了.

这是可卡因的一个问题.似乎paperclip依赖可卡因只能说它必须是Cociane> 0.02.最新版本的Cocaine 0.4.2(在撰写本文时)有一个新的API,它不向后兼容.你需要降级到可卡因0.3.2.

只需将它放在回形针之前的Gemfile中:

gem "cocaine", "0.3.2"
