rails paperclip and passenger `is not recognized by the 'identify' command`

Question

When I upload a photo, my model fails validation, err well even without any validations I\'m returned this error:

/tmp/stream20100103-13830-ywmerx-0 is not r         


        

Answer 1

This is related to ImageMagick. The command_path option needs to point to the location where identify is installed. From the command line, you can determine this with which identify.

$ which identify
/some/path/to/identify

Afterwards, set command_path to that path (in config/environments/development.rb):

Paperclip.options[:command_path] = "/some/path/to"
