Paperclip::Errors::NotIdentifiedByImageMagickError in Rails 4

问题

There is the following model:

class Picture < ActiveRecord::Base
  belongs_to :business

  has_attached_file    :image, styles: { medium: "640x260>" }
  validates_attachment :image, content_type: { :content_type => /\Aimage\/.*\Z/ }
end

Also I've installed 'imagemagick' using brew (I use Mac OS). But when I was trying to execute the following code

@picture = business.pictures.build(picture_params)
@picture.save

def picture_params
    params.require(:picture).permit(:image)
end

I got the following error: An error was received while processing: #<Paperclip::Errors::NotIdentifiedByImageMagickError: Paperclip::Errors::NotIdentifiedByImageMagickError>

I was trying to update PNG file:

= form_for [:admin, business, @picture] do |f|
    .row
        = f.file_field :image
        = f.submit 'Add'

How can I fix my problem?

回答1:

I had the same issue. I resolved this by reinstalling the imagemagick.

brew uninstall imagemagick jpeg libtiff
brew install imagemagick

Link freetype before installing imagemagick if it is not linked

brew link freetype

verify imagemagick using identify you should get something like this:-

milind@ubuntu:~/workspace/latest$ identify
Version: ImageMagick 6.6.9-7 2014-03-06 Q16 http://www.imagemagick.org
Copyright: Copyright (C) 1999-2011 ImageMagick Studio LLC
Features: OpenMP   ....

and add this to development.rb(knowing your path where imagemagick is installed)

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