Paperclip - imagemagick Configuration

I’m not sure what changed, but I started getting errors from the
paperclip plugin:

[paperclip] An error was received while processing:
#<Paperclip::NotIdentifiedByImageMagickError: /tmp/stream.13688.0 is
not recognized by the ‘identify’ command.>

I have verified the command path is correct. What else should I be


I figured it out! I was setting my options like this (which used to

Paperclip::Attachment.default_options.merge!(:command_path => “/usr/

But I noticed others using this method, which solved my problem!

Paperclip.options.merge!(:command_path => “/usr/local/bin”)

I hope this helps someone else!


This did the trick for me! Thanks for sharing!

Also for other peoples benefit:

For windows, make sure you close down the rails server and any command
prompt instances and restart them. The imagemagick install path in
program files (the folder containing identify.exe) needs to be
accessible in the PATH variable. To check type echo %PATH% in the
command prompt. If the imagemagick installation folder shows, the
rails app should function.
