Question

我刚从一个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.

像paperclip正在寻找名为＆＃39; file＆＃39;的文件。但我不确定为什么。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。

有什么想法吗？

它是纸夹中的一个错误，它不能正确解析命令的内容。我深入挖掘回形针来找到：

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。我在命令行上运行以下命令验证了这一点：

identify :file

手动修补替换手册会产生类似事情发生的其他错误。

好的，我设法解决了。

这是可卡因的一个问题。似乎paperclip依赖于可卡因，只能说它必须是Cociane＆gt; 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。

在回形针之前简单地将它放在你的Gemfile中：

gem "cocaine", "0.3.2"

找不到回形针文件错误
