Can't install RMagick 2.13.1. Can't find MagickWand.h. - ruby

Question

When I try do install rmagick I get the following error message:
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.
I'm on Mac OSX 10.6.8, ruby 1.9.2p290, rvm 1.10.2.
Can anyone help me please to solve this problem.

Answer 1

If you're on Ubuntu, installing this package is what fixed it for me:
sudo apt-get install libmagickwand-dev

Answer 2

It looks like ImageMagick 7 changed include file path.
On building rmagick, since it includes file as wand/MagickWand.h There are no workarounds. It looks like sticking with ImageMagick 6 for now.
On Mac OS X (I tested on Sierra), I used HomeBrew's versions tap like:
brew tap homebrew/versions
brew install imagemagick#6
Then, use the path shown on above installation:
PKG_CONFIG_PATH=/usr/local/opt/imagemagick#6/lib/pkgconfig gem install rmagick
To install with ImageMagick 6.

Answer 3

I didn't want to mess with environment variables since I wanted bundler to be able to compile this gem on its own on a CI machine. Instead, I used Homebrew to install pkg-config:
brew install pkgconfig
and the next time I tried compiling the RMagick gem it found the header file without issue.
(This is pkg-config 0.28, ImageMagick 6.8.0-10, and RMagick 2.13.2, all on Mountain Lion.)

Answer 4

I had a similar issue with running
$ gem install rmagick
First of all, do you have imagemagick installed? If you're not sure, run
$ 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
It worked for me after I did this.

Answer 5

fix this setting the include path of your current imagemagick installation:
Install ImageMagick with brew
brew install imagemagick
find library
$ mdfind MagickWand.h
/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/wand/MagickWand.h
Install rmagick gem
$ C_INCLUDE_PATH=/path/MagickWand.h gem install rmagick
example:
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.5-7/include/ImageMagick/ gem install rmagick

Answer 6

I marked this as a favorite because it seems to come back to bite me with every new system I need to install RMagick on (and time has passed and version numbers have rolled).
Mac OS X 10.8.4
rvm 1.22.3
ruby-2.0.0-p247
Xcode 4.6.3 developer tools installed
$ brew install imagemagick
==> /usr/local/Cellar/imagemagick/6.8.6-3
$ brew install pkgconfig
==> /usr/local/Cellar/pkg-config/0.28
$ C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.8.6-3/include/ImageMagick-6 PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.8.6-3/lib/pkgconfig/ gem install rmagick
Successfully installed rmagick-2.13.2
Many thanks to everyone who added helpful answers above!

Answer 7

Mac users using brew
If you can use v6 of ImageMagick instead of 7, you can try this
brew install imagemagick#6 --force && brew link imagemagick#6 --force
Note this will unlink your existing IM installation, so be careful if you have other projects on your machine using ImageMagick without problems.

Answer 8

For my own and others edification, I got past the error about the magicwand.h by using the suggestion xonico. MDFind plus the C_INCLUDE_PATH. However, it then gave me an error about MagickCore.pc. My final command to get this working had to include both like so:
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick/ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/lib/pkgconfig/ gem install rmagick
Obviously your paths will vary depending on whether you're using brew like me and what version of imagemagick you were installing. Also, xcode command line tools did have to be installed, as others have mentioned.
Thanks for everyone's posts on this! I am plussing your answers since it contributed to mine!

Answer 9

For Ubuntu:
sudo apt-get install imagemagick libmagickwand-dev
gem install rmagick

Answer 10

I had a problem after update to Maverics.
It have lost a lot of linkings.
In my case I had to refresh links to pkg-config
brew unlink pkg-config
brew link pkg-config
Then installing rmagick worked like a charm.

Answer 11

I updated to Mountain Lion and started getting this same problem. I had to re-install brew, XCode, the XCode tools - pretty much the whole environment!
I eventually solved this problem using the answer from phopkins above...
brew install pkgconfig
Once that was successfully completed (I had to delete some old symlinks first) then I was able to successfully install the RMagick gem

Answer 12

This worked for me on Mac OsX
Install Imagemagick:
brew remove imagemagick
brew install imagemagick
Make sure pkg-config is correctly linked:
brew uninstall pkg-config
brew install pkg-config
brew unlink pkg-config && brew link pkg-config
Install gem
gem install rmagick

Answer 13

For Ubuntu users:
It will never done directly on Ubuntu. You should first install packages to run this command...:
sudo apt-get install libmagickwand-dev
...and then do install:
gem install rmagick
You may get the same issue, for that, Try clearing your apt repository and removing any broken packages first:
sudo apt-get update
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get autoremove
If the system identifies any broken packages, forcefully remove them (replace package_name with your own):
sudo dpkg --remove -force --force-remove-reinstreq package_name
Then re-install any missing packages again. :)

Answer 14

An issue for me was that rmagick is out of date and not updated regularly. If you have too new of an ImageMagick version, then it might not be compatible. Check your version of ImageMagick using the following:
$ convert --version
If the ImageMagick version is > 7, it is not compatable with rmagick. The user will get errors such as
Can't install RMagick 2.16.0. Can't find MagickWand.h.
*** extconf.rb failed ***
Go back to version six of ImageMagick until they update rmagick to be compatible with version seven of ImageMagick. Someone has hosted the appropriate version(6) in a separate gem - 'imagemagick#6'.
If you need rmagick to work but currently have an imagemagick version 7 or higher, here are the steps to switch:
$ gem install imagemagick#6
$ brew unlink imagemagick
$ brew link imagemagick#6 --force

Answer 15

Helped me on Debian Wheezy 64bit
apt-get install libmagickcore-dev libmagickwand-dev

Answer 16

Try reinstalling both Imagemagick and PkgConfig. That should fix it for Mavericks
brew update && brew upgrade
brew reinstall imagemagick
brew reinstall pkgconfig

Answer 17

C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.7.7-6/include/ImageMagick gem install rmagick

Answer 18

I was really struggling with this on OS X Mountain Lion (after upgrading from Lion) and none of the suggestions regarding C_INCLUDE_PATH, PKG_CONFIG_PATH, ln'ing various files, etc., were working. On the same day I upgraded to Mountain Lion, I also upgraded XCode to 4.5.2, but I didn't really think too much of this.
Eventually I stopped trying to install RMagick and had to pass on the work to a colleague.
Then, by chance, I found that I was trying to use bundle install on another project and I wasn't able to install the json gem because "make" could not be found. I checked into that and found you need to go to XCode -> Preferences -> Downloads and install the command line tools to get make working again. The json gem installed fine.
Then I paused...and tried
gem install rmagick
One more time. It worked perfectly.

Answer 19

for a rails based application, I found this
sudo apt-get install -y libmagickwand-6-headers
C_INCLUDE_PATH=/usr/include/ImageMagick-6 gem install rmagick
bundle update rmagick
bundle install
worked on debian jessie

Answer 20

I ran into this because I'd run OS X's Migration Assistant and nothing was relinked after the migration. You need to check the output of Wand-config --ldflags --libs. In my case it gave:
$ Wand-config --ldflags --libs
/usr/local/bin/Wand-config: line 50: pkg-config: command not found
/usr/local/bin/Wand-config: line 53: pkg-config: command not found
After relinking pkg-config, libpng, and libfreetype, that became:
$ Wand-config --ldflags --libs
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
-L/usr/local/Cellar/imagemagick/6.8.8-9/lib -lMagickWand-6.Q16 -lMagickCore-6.Q16
And then:
$ gem install rmagick
Building native extensions. This could take a while...

Answer 21

In linux OS:
C_INCLUDE_PATH=/usr/local/include/ImageMagick-6/ gem install rmagick
Building native extensions. This could take a while...
ERROR: Error installing rmagick:
ERROR: Failed to build gem native extension.
/home/vagrant/.rvm/rubies/ruby-1.9.3-p0/bin/ruby extconf.rb
...
Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
then:
export PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
in my .bashrc file to pick up MagickCore.pc, then created two symlinks:
ln -s /usr/local/include/ImageMagick/wand /usr/local/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/local/include/ImageMagick-6/magick
Now:
$ gem install rmagick
Building native extensions. This could take a while...
Successfully installed rmagick-2.13.2
1 gem installed
boom everything works fine.

Answer 22

At arch linux, after installing imagemagick#6, gem wasn't able to install package rmagick and got error below.
Can't install RMagick 2.16.0. Can't find MagickWand.h
Worked for me using below steps
added pkgconfig path to .bashrc
export PKG_CONFIG_PATH="/usr/lib/imagemagick6/pkgconfig"
Created two symlinks as below
ln -s /usr/include/ImageMagick-6/wand /usr/include/ImageMagick-6/wand
ln -s /usr/local/include/ImageMagick/magick /usr/include/ImageMagick-6/magick

Answer 23

There are some variants to this problem. Mostly the case is dealing with a legacy application that run older versions of ruby.
rmagick has a dependancy on imagemagick... but not just any. If you've gone too far ahead, it may be wise to backtrack:
brew uninstall imagemagick
Then proceed with an appropriate version
brew install imagemagick#6
then you path needs to be adjusted and forced upon homebrew
export PATH="/usr/local/opt/imagemagick#6/bin:$PATH"
brew link --force imagemagick#6
then you can install rmagick to most recent or versioned
gem install rmagick -v '2.15.4' --source 'https://rubygems.org/'

Answer 24

I had a hard time getting this same issue to work when I had a default ImageMagick install on OSX 10.8 (no homebrew or macports). No combination of the suggestions in this thread or threads linked to from this thread worked for me (modifying the paths for my local install of course).
I simply deleted the default ImageMagick 6 install, and then reinstalled with macports. My rmagick install worked immediately after with no other changes.

Answer 25

on OSX Maverick 10.9.1
it took me ages to figure it out but I solved these issues the following way:
nano /etc/paths
changed:
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
into:
/usr/local/bin
/usr/bin
/bin
/usr/sbin
/sbin
that that local stuff, like 'brew' is loaded first.
now I hit 'brew doctor' into the terminal, to see if there's something messed up
if you get the following output
Your system is ready to brew.
everthing is fine. if not ti will tell you what to do. Like kick out unbrewed stuff, broken libs, clean symlinks and whatnot.
When you are ready to brew, you need ghostscript(for pdfs), libpng, imagemagick via brew.
then you can happily type : 'gem install rmagick', in case you did't kill your ruby setup. But thats easy to reinstall via your cleaned up brew.
PS:
another helpful command is: 'which convert', to show you what version of imagemagick is used by the system.
as well as --version
so if you installed git via brew and do 'git --version' and it returns some apple git version, your load path is broken...

Answer 26

On Mac OS X 10.9, try to update your Xcode if there's a warning about it.
$ brew doctor
I you found some warning, do:
$ sudo /Developer/Library/uninstall-developer-folder
Then try:
$ bundle install
again
That worked fine for me.

Answer 27

On CentOS 6.5 x64, it was pretty easy:
yum install ImageMagick ImageMagick-devel
gem install rmagick -v '2.13.2'

Answer 28

I was able to fix this by upgrading to 2.13.2

Answer 29

All brew options failed to install rmagick 2.13.1 on yosemite 10.10
this worked
get the latest RVM
\curl -sSL https://get.rvm.io | bash -s stable --ruby
rvm install 2.1.1
rvm use 2.1.1
download and install the package file
http://cactuslab.com/imagemagick
(I used pacifist to install)
Confirm location of MagickCore.pc file
mdfind magickcore.pc
eg. /opt/ImageMagick/lib/pkgconfig/MagickCore.pc
Manually download rmagick-2.15.2.gem file
https://rubygems.org/gems/rmagick/versions/2.15.2
from that dir
sudo C_INCLUDE_PATH=/opt/ImageMagick/include/ImageMagick-6/ PKG_CONFIG_PATH=/opt/ImageMagick/lib/pkgconfig gem install --local rmagick-2.15.2.gem
If you are having issues with bundle installer still complaining about 2.13.1
In your gem file / gem.lock file upgrade ALL dependencies
rmagick (2.13.1) - > rmagick (>= 2.15.2)

Answer 30

Got same error for alpine 3.9 image build. It comes with ImageMagick 7.0.8.38-r0
To fix that you either use alpine 3.5 with ImageMagick 6.9.6.8-r1:
FROM alpine:3.5
Or install ImageMagick 6.9.6.8-r1 with package repository for 3.5:
RUN apk add imagemagick-dev=6.9.6.8-r1 --repository http://dl-3.alpinelinux.org/alpine/v3.5/main/
There is an open issue in rmagick repo regarding failed builds for ImageMagick 7.0.x. so hopefully it will be fixed soon.
