Can't install rmagick in Mountain Lion

Question

Tried installing rmagick in Mountain Lion with sudo gem install rmagick and got the following. Any help is appreciated. None of the forum answers worked.

Can't install RMagick 2.13.1. Can't find the ImageMagick library or one of the dependent libraries. Check the mkmf.log file for more detailed information.

Answer 1

This worked for me...

As stated on earlier answers:

$ brew remove imagemagick
$ brew install imagemagick --disable-openmp --build-from-source

I got the magicwand.sh :

$ mdfind MagickWand.h -->
/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/wand/MagickWand.h

I then took out the whole path except the actual filename and added C_INCLUDE_PATH= eg:

/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/wand/
--->
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/

I then looked for MagickCore.pc

$ mdfind MagickCore.pc
/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/MagickCore.pc

The same for this as before:

/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/
--->
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/

I then used these two paths with gem install:

$ sudo C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/include/ImageMagick/ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/ gem install rmagick

And it finally worked after hours of research. Hope it helps someone.

Reinstall imagemagick with Homebrew:

brew remove imagemagick
brew install imagemagick --disable-openmp --build-from-source

Or you can install using this shell script::

I've been struggling with this Rmagick on Mountain Lion installation issue for a while, and tried MANY different solutions, and this is the one that finally did the trick for me :

Reinstall imagemagick with Homebrew:

$ brew remove imagemagick
$ brew install imagemagick --disable-openmp --build-from-source

and then

$ gem install rmagick -v '2.13.2'
