I have been banging my head against this for several days. Recently, my image uploader has stopped working properly. I have investigated several possibilities, but have none of the suggested solutions have worked in my case.
The error message is:
#<Paperclip::Errors::NotIdentifiedByImageMagickError:Paperclip::Errors::NotIdentifiedByImageMagickError>
Here are the details:
- Mac OS X 10.8.3
- ImageMagick 6.8.4-4 2013-03-29

development.rb contains appropriate path (and I have verified that it is correct using which identify)

What I've tried.
- I've made sure that the image name is simple (USB2230.jpg), no colons.
- I've updated the version of ImageMagick to the most recent.
- I've also re-downloaded and reinstalled the CommandLine Tools for 10.8.3 (someone suggested that the issue might be related to an outdated libtool).
- I've rebooted the computer.
I've tried variations on gem versions including
# variation 1 gem 'paperclip', '~> 2.8.0' gem "cocaine", "=0.3.2" # variation 2 gem "paperclip", "~> 3.4.0" gem "cocaine", "= 0.4" # variation 3 (which is what is reflected in the included Gemfile.lock info above). gem "paperclip", "~> 3.4.0"
If I remove the scaling,
:styles => {:show => "1200x500#", :medium => "300x300#", :thumb => "100x100>"},
:convert_options => {:show => "-gravity center"}
the upload works, but I kind of need the scaling ;-)
Can anyone see something I am missing?
