Installing RMagick gem — Can't find MagickWand.h

Question

I am installing the rmagick gem on OSX 10.6.8, using gem install rmagick, and I am getting the following error

    Can\'t install RMagick 2.13.1         


        

Answer 1

I am on OS X El Capitan.

My app is using ruby 2.1.2 and rmagick 2.13.4.

When using brew install imagemagick I get ImageMagick -v 7.0.4-5.

The solution for me was to use brew install imagemagick@6 which gave me ImageMagick -v 6.9.7-5 which allowed me to successfully install the gem.

Here's a solution for OS X Mavericks - at least it worked for me...

First, install Xcode 5 (from the App Store)

Then install development-tools - open Terminal and type:

xcode-select install

Next, grab the ImageMagick package from CatusLab: http://cactuslab.com/imagemagick/ (I opted for the package without Freetype support, that requires XQuarz - but it's really up to you).

You'll need pgkconfg as well - get it here: http://macpkg.sourceforge.net

Once installed, export the pkgconfig binary:

export PATH=/opt/pkgconfig/bin:$PATH

Then find the MagickWand.h

mdfind MagickWand.h

it puts out the path to MagickWand.h, in my case /opt/ImageMagick/include/ImageMagick-6/wand/MagickWand.h

Next find the pkgconfig path:

mdfind MagickCore.pc

For me it put out: /opt/ImageMagick/lib/pkgconfig/MagickCore.pc

I had the problem that rmagick gem couldn't be fetched so I downloaded it from rubygems.org/gems/rmagick

With the rmagick gem downloaded to your Download folder you should now be able to install rmagick:

sudo C_INCLUDE_PATH=/opt/ImageMagick/include/ImageMagick-6/ PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig/ gem install --local ~/Downloads/rmagick-2.13.2

For me it installed successfully - hope this helps...

Answer 3

I wasted a lot of time on this, ImageMagick versions above 6.7 don't play nicely with the installation of the rmagick gem. It looks like someone made a package to address this issue, try:

brew install imagemagick-ruby186

After uninstalling your previous imagemagick. Afterwards gem install rmagick worked fine for me.

here's what i did on 16.04.1,

sudo apt-get install libmagickwand-dev
sudo apt-get install graphicsmagick-imagemagick-compat

and then install gem

PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH" gem install rmagick -v '2.13.2'

Answer 5

I had a similar issue with running

$ gem install rmagick

then check the version by typing

$ convert --version

If you do, you probably either installed it with fink or macports (maybe homebrew?). What is happening is that rvm can't find the imagemagick directory.

After reading https://superuser.com/questions/361435/i-have-compiled-imagemagick-on-my-centos-and-rmagick-wont-install I exported the imagemagick path by adding

$ export PKG_CONFIG_PATH="/opt/local/lib/pkgconfig:$PKG_CONFIG_PATH"

to my ~/.bash_profile, sourcing the new profile, then running gem install rmagick again.

this worked for me try

if the above solution doesnt work then try following command

sudo apt-get install libmagickwand-dev

this will help i hope.

Answer 6

For Debian-based (e.g., Ubuntu) systems you can try,

sudo apt-get install libmagickcore-dev libmagickwand-dev
gem install rmagick

it works for me.
