Paperclip error - NotIdentifiedByImageMagickError

Question

I'm trying to upload images to aws s3 with paperclip but I get this error

Command :: file -b --mime '/var/folders/d_/k4_ps9hj5fj_3df5t210vjym0000gn/T/2611a2396a4af6938e5c5867c8bb409f20140515-7787-1u773ft.jpg'

In my model, I set up these styles

 has_attached_file :photo, :storage => :s3, :s3_credentials => "#{Rails.root}/config/s3.yml", :path => "/:style/:id/:filename", :styles => { :medium => "300x300>", :thumb => "100x100>" }, :default_url => "/assets/profile/iama.png"

When I remove these styles, everything works, but I really need them.

I'm using Rails 3.2.16 and

  paperclip (4.1.1)
      activemodel (>= 3.0.0)
      activesupport (>= 3.0.0)
      cocaine (~> 0.5.3)
      mime-types

I already installed ImageMagick and the rmagick gem

Help me please.

Answer 1

The problem was that my ImageMagick didn't have JPEG delegates. I found out using convert -list format. So I reinstalled ImageMagick using MacPorts and reinstalled rmagick with the new Paths to ImageMagick.

Answer 2

I had similar issue and updating imagemagick resolved that. You might want to try that out as well.

Answer 3

I had the same problem on my mac. Resolved it by installing GhostScript

brew install gs

as paperclip documentation says: http://rdoc.info/gems/paperclip/frames/file/README.md

Answer 4

In my case I had a dirty ImageMagick installation (v7.0) that I installed manually before using rpm. This one doesn't showed me all dependencies that ImageMagick needed so Paperclip crashed when it tried to use convert or identify commands.

I recommend, for Unix users to install using yum or apt-get for installing all the dependencies correctly. Also recommend to install ghostscript in case that commands identify and convert cannot be summoned from paperclip.

cd ImageMagick-7.0.3-0
make uninstall
yum install ImageMagick ImageMagick-devel

Please follow this link for more specific details: How to Install ImageMagick on CentOS & RHEL

Rubygems used: paperclip (5.1.0) cocaine (0.5.8)

Answer 5

Installing libmagickwand-dev seemed to sort it out.

1. sudo apt autoremove imagemagick
2. rm /usr/bin/convert and rm /usr/bin/convert-im6
3. sudo apt-get install imagemagick
4. sudo apt-get install libmagickwand-dev

sudo apt install ffmpeg

Answer 6

I had the same problem, and in addition to reinstalling everything (ImageMagick, libtool, ghostscript, jpeg), and finally running a general brew update && brew upgrade, I also had to relink freetype:

brew unlink freetype && brew link freetype

Answer 7

I had the same problem but i remove styles and applicattion started works

has_attached_file :picture
validates_attachment_content_type :picture, content_type: /^image\/(png|gif|jpeg|jpg)/

Answer 8

I also faced the same problem on Ubuntu 18 server.

You can check for the delegates installed with Imagemagick using the below command:

convert --version

I found some missing delegates after installs like the JPEG/JPG or PNG.

I purged the Imagemagick packages and then installed the required dependencies for JPEG/JPG and PNG using below command:

sudo apt-get install build-essential checkinstall libx11-dev libxext-dev zlib1g-dev libpng12-dev libjpeg-dev libfreetype6-dev libxml2-dev

Then tried to install Imagemagick with the latest version and it worked.
