Error in rmagick installation in ruby and rails

Question

Hiall,

I am new to ROR. I am trying to install rmagick on my local machine. When I try to install it everytime i get the following error: Please help me out with this situation.

D:\ruby\bin>gem install rmagick  --platform=ruby -- --with-opt-lib=D:\ruby\Rmmagik\lib --with-opt-include=D:\ruby\Rmmagik\include   Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing rmagick:

Can't install RMagick 2.13.1. Can't find MagickWand.h.
*** extconf.rb failed ***
Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
 --with-opt-dir
 --without-opt-dir
 --with-opt-include=${opt-dir}/include
 --with-opt-lib=${opt-dir}/lib
 --with-make-prog
 --without-make-prog
 --srcdir=.
 --curdir
 --ruby=D:/ruby/bin/ruby
Gem files will remain installed in D:/ruby/lib/ruby/gems/1.8/gems/rmagick-2.13.1 for inspection.
Results logged to D:/ruby/lib/ruby/gems/1.8/gems/rmagick-2.13.1/ext/RMagick/gem_make.out

Thanks in advance

You're missing a header file.

It looks like you're on Windows, right?

If so, a simple solution may be to download the pre-built ImageMagick binary for Windows.

Link

If you're on Debian or Ubuntu:

sudo apt-get install imagemagick libmagickcore-dev libmagickwand-dev

(Editors, feel free to add solutions for other platforms)
