Spree :: Admin :: ImagesController #create中的Paperclip :: NotIdentifiedByImageMagickError

Question

我试图第一次设置Spree.一切顺利,直到我上传图片.我在Mac OSX Mountain Lion上使用自制软件安装了Imageamgick.上传任何图像会给我以下错误.

Paperclip::NotIdentifiedByImageMagickError in Spree::Admin::ImagesController#create

    Command :: identify -format %wx%h :file
[paperclip] An error was received while processing: #<Paperclip::NotIdentifiedByImageMagickError: /var/folders/fq/9g_6hmg513g6137rb6sbghw00000gn/T/stream20121005-26943-16883d4.png is not recognized by the 'identify' command.>

Paperclip::NotIdentifiedByImageMagickError (/var/folders/fq/9g_6hmg513g6137rb6sbghw00000gn/T/stream20121005-26943-16883d4.png is not recognized by the 'identify' command.):

当我从命令行运行识别时,我得到以下输出

  -log format          format of debugging information
  -version             print version information

By default, the image format of `file' is determined by its magic
number.  To specify a particular image format, precede the filename
with an image format name and a colon (i.e. ps:image) or specify the
image type as the filename suffix (i.e. image.ps).  Specify 'file' as
'-' for standard input or output.

任何帮助将不胜感激.

谢谢,科里

我的错误是 - " Spree :: Admin :: ImagesController中的Paperclip :: NotIdentifiedByImageMagickError "

我几天前修正了这个错误.

在此之前我试过:

• 更新XCode(使用命令行工具)
• 更新Imagemagick(我从源代码和二进制模块中尝试过)
• 更新MacPort
• 使用Brew(使用Imagemagic的所有依赖项刷新,使用"brew doctor"),而不是MacPort
• 重新安装使用Imagemagick的所有gem
• 捆绑更新
• 等等

确定我在production.rb文件中指向Imagemagick bin文件夹的"Paperclip :: Attachment.default_options [:command_path]"选项.

好几次,我一次又一次地从a到z做过.

但没有什么可以帮助我.

顺便说一句,在所有情况下,我都使用任何类型的测试图像进行了很好的"转换","识别"和"显示",但不是在我的rails应用程序(狂欢应用程序)中.

我潜入了北斗,并尝试在rails console内进行研究

Paperclip.run("identify", "-format %m :file", :file => "/path/to/image”) 

像回形针一样.并且只有这个命令的新格式(可卡因0.4):

Paperclip.run("identify", "-format %m /path/to/image")

工作得很好!!!

结果,我发现可卡因0.4是我问题的根源.我尝试在我的Gemfile中降级为可卡因0.3.2并且我的Spree应用程序开始工作!

我需要做的就是使用可卡因0.3.2而不是0.4!
