Hi,

An error occurred while installing rmagick (2.13.3), and Bundler cannot continue.

Make sure that `gem install rmagick -v '2.13.3'` succeeds before bundling.

I tried everything i found on the internet.. after a few days i found the solution:

Make sure you have installed ImageMagick:

 brew install ImageMagick

Then i searched for "MagickWand.pc" file.

sudo find / -name "MagickWand.pc"

It was in:

/usr/local/Cellar/imagemagick/6.9.2-4/lib/pkgconfig

So to solve this i added this path to the env variable "PKG_CONFIG_PATH"

export PKG_CONFIG_PATH="/usr/local/Cellar/imagemagick/6.9.2-4/lib/pkgconfig"

After this i was able to run "bundle install" correctly.

Best,
Waldi
