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

Question

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

Answer 3

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
