Is there not a gem for imagemagick?
I'm on Mac OS and if I do 'brew install imagemagick' it works, and I get passed my problem.
Error in browser network tab: [ "Unable to process image ... : You must have ImageMagick or GraphicsMagick installed" ]
I tried the rmagick gem but that doesn't seem to be doing the trick either. I want this in a gem file so other devs can get this working without having to brew install it. Anyone know what I'm missing here?
