Help with Paperclip and ImageMagick on windows


I am hoping someone has run into this issue and can help!!!

I am running into an issue and been struggling for a couple of days.
Hoping you can point me in the right direction :slight_smile:

I am developing on Windows Vista in Eclipse.

I am using Paperclip to add documents as attachments and create
thumbnails. I have ImageMagick installed. The attachments are
uploading no problem however when I try to create thumbnails I get the
following error:

I have edited the command path in paperclip.rb to:

# :image_magick_path => nil,

        :command_path => "C:\Program Files\ImageMagick-6.6.2-

I have also added the following line in environments/development.rb

Paperclip.options[:command_path] = "C:\Program Files
\ImageMagick-6.6.2- Q16"

The model looks like:

class Collection < ActiveRecord::Base

  belongs_to :user

  validates_presence_of :name, :on => :create, :message => "can't be

  validates_presence_of :description, :on => :create, :message =>
"can't be blank"

  # Paperclip
  has_attached_file :work,

                    :styles => { :thumb=> "100x100#",

                                  :small => "150x150>",

                                  :medium => "300x300>",

                                  :large => "400x400>" }

  validates_attachment_presence :work

  validates_attachment_content_type :work,

                                    :content_type => ['image/jpeg',















The upload of documents works fine if I comment out the styles action.

When I try to create thumbnails with the styles action I get the
followign browser error:

undefined method `exitstatus' for nil:NilClass

and I see the followign in the trace log:

I suspect that although I have defined the windows path to ImageMacick
paperclip is still trying to look for the ImageMighc Identify binary
in the unix directory structure : /usr/loacl/bin. Hence the error:

No such file or directory - /usr/local/bin/identify '-format'

Any suggestion will help greatly... I have been strugling with this
for a few days now... Thanks
