Question

Rails 4 PaperClip ImageMagick Content Type Error for Images

I’m using ImageMagick and Paperclip for uploading images to my Rails app. It is working on my development machine, a Mac, but not here. When Paperclip tries saving different sizes of the images, ImageMagick give the error

Paperclip::Errors::NotIdentifiedByImageMagickError

I’m using Paperclip 4.2.1. In my Rails model I have:

has_attached_file :photo_image, :styles => { :medium => "330x250#", :small => "150x120#", :thumb => "120x100#" }, 
                                :url => "/system/dadverts/:attachment/:id/:style/:filename",
                                :path => ":rails_root/public/system/dadverts/:attachment/:id/:style/:filename",
                                :default_url => "300250ad.png"
                                
validates_attachment_content_type :photo_image, :content_type => /\Aimage/

In my production environment settings I have:

Paperclip.options[:command_path] = "/usr/local/bin/"

I’ve run sudo apt-get update a couple of times but this has not resolved the issue.

Any suggestions on what could be wrong would be appreciated.

I’m finally back trying to fix my ImageMagick problem. I ran a search and found I have several references to ImageMagick with different version numbers. I installed version 6.9.0 from source, which only works with GIFs. How do I clean this up to install as suggested by ash?

find / -name ImageMagick /usr/lib/x8664-linux-gnu/ImageMagick-6.7.7 /usr/share/ImageMagick-6.7.7 /usr/share/man/man1/ImageMagick.1.gz /usr/local/lib/pkgconfig/ImageMagick++.pc /usr/local/lib/pkgconfig/ImageMagick-6.Q16.pc /usr/local/lib/pkgconfig/ImageMagick.pc /usr/local/lib/pkgconfig/ImageMagick+±6.Q16.pc /usr/local/lib/ImageMagick-6.9.0 /usr/local/etc/ImageMagick-6 /usr/local/include/ImageMagick-6 /usr/local/include/ImageMagick-6/magick/ImageMagick.h /usr/local/share/ImageMagick-6 /usr/local/share/man/man1/ImageMagick.1 /usr/local/share/doc/ImageMagick-6 /usr/local/share/doc/ImageMagick-6/images/ImageMagick.ico /usr/local/share/doc/ImageMagick-6/www/api/MagickCore/ImageMagick8h-source.html /usr/local/share/doc/ImageMagick-6/www/api/MagickCore/ImageMagick_8h.html /usr/local/share/doc/ImageMagick-6/www/ImageMagickObject.html /usr/local/share/doc/ImageMagick-6/www/Magick++/ImageMagick.png /etc/ImageMagick

Can I just delete “/usr/local/lib/ImageMagick-6.9.0”?

asb, I checked the list and found that JPEG and PNG were missing from the list. I’ll try your suggestion and let you know how it goes. Do you think I should delete the current installation and start over? If so, what recommendations would you have for making sure I get it all and not leave anything behind that would cause any conflicts?

Thanks.

The List.
