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

问题

I am attempting to setup Spree for the first time. Everything was going well until I hit the image upload. I have installed Imageamgick using homebrew on Mac OSX Mountain Lion. Uploading any image gives me the following error.

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.):

When I run identify from the command line I get the following output

  -list type           print a list of supported option arguments
  -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.

Any help would be greatly appreciated.

Thanks, Cory

My error was - “Paperclip::NotIdentifiedByImageMagickError in Spree::Admin::ImagesController”

I fixed this error some days ago.

Before that I tried:

Update XCode (with Command-Line Tools)
Update Imagemagick (i tried it from source and as binary module)
Update MacPort
Used Brew (refreshing with all dependencies for Imagemagic, used “brew doctor”), not MacPort
Reinstall all gems that use Imagemagick
Bundle update
etc

And sure I had my “Paperclip::Attachment.default_options[:command_path]” option in production.rb file pointing to Imagemagick bin folder.

Several times i did it from a to z, again and again.

But nothing could help me.

By the way, in all cases i had worked fine “convert”, “identify” and “display” with test images of any kind, but not in my rails app (spree app).

I dived dipper and tried to do research inside rails console with

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

as paperclip do. And only new format (cocaine 0.4) of this command:

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

worked fine!!!

As a result, i found that cocaine 0.4 is the source of my problem. I tried downgrade to cocaine 0.3.2 in my Gemfile and my Spree app start working!!!

All i need to do is use cocaine 0.3.2 instead of 0.4!!!

Check if png format is in the list of compiled formats of identify:

identify -list format

If it's not, you might have to recompile it with these options:

./configure --prefix=/usr/local --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes

Also I met the problem when image file doesn't exists in public folder.
I've just copied a random file with the same name and everything started work.

parepclip 2.7.5 cocain 0.3.2
