An error occurred while installing rmagick (4.2.4), and Bundler cannot continue.
Make sure that `gem install rmagick -v '4.2.4' --source 'https://rubygems.org/'` succeeds before bundling.
In Gemfile:
rmagick
I have installed pkg-config and imagemagick@6 with homebrew
I have followed various SO answers to debug, but nothing is working. How can I install rmagick ?

There is currently a clash with the homebrew installed "highway"
workaround to get rmagick installed
brew install pkg-config imagemagick
brew uninstall highway
bundle install
brew install highway
