ImageMagick 7 with RMagick 2.16 on MacOS Sierra Can’t find MagickWand.h
I have just encountered and solved this issue on a new Mac running Sierra. There seems to be no solution for ImageMagick 7 at this time.

rmagick and OS X Lion
I had the same problem and resolved it by uninstalling ImageMagick, removing the rmagick gem and running bundle install again. Make sure the rmagick gem is completely gone from your ~/.rvm/gems/ruby-1.8.7-p334/gems/ folder before re-installing and running bundle install and it should at least get you beyond that error.

Resize existing images to new style in paperclip & RMagick
You want the reprocess! method of Paperclip::Attachment. See the docs. class User < ActiveRecord::Base has_attached_file :avatar, :styles => { :medium => “300×300>”, :thumb => “100×100>” } end # Console… >> User.find_each { |u| u.avatar.reprocess! } Also, according to the comments before the reprocess! method, there’s a paperclip:refresh Rake task, which might be easier.

Error installing Rmagick on Mountain Lion
It appears it’s a problem reported on the Homebrew github repo (https://github.com/mxcl/homebrew/issues/16625) blaming rmagick itself not supporting newer versions of imagemagick.
