Whenever I try to install rmagick I get ERROR: Can't install RMagick 4.2.6. Can't find ImageMagick with pkg-config. I tried all the other options, with installing imagemagick#6, setting PKG_CONFIG_PATH, unlinking, reinstalling & linking imagemagick, setting the pkg-config path from the lib folder of imagemagick, nothing worked.
More detailed error:

I used to get an error and also the rmagick installation issue:
pkg-config --list-all
[1] 664 segmentation fault pkg-config --list-all
pkg-config has version 0.29.2, I tried both removing the proj.pc file and changing it to the details from this comment.
pkg-config --exists --print-errors "proj" even returns nothing, so I don't think there's an error on that side.
I managed to fix the issue by uninstall highway (brew uninstall highway), because it has a conflict over a variable. Running pkg-config --debug --list-all will show that.
While I'm trying to install rmagic, it shows following error

I'm using MacOS sierra, ruby version 2.2.3
I had this issue a while back. You need to install imagemagick. Per the github repo for the rmagic gem
Pre-reqs:
ImageMagick Version 6.4.9 or later. You can get ImageMagick from www.imagemagick.org.
I believe you can also install it with brew
$ brew install imagemagick#6
$ brew link imagemagick#6 --force
$ gem install rmagick
brew unlink pkgconfig
bundle install
brew link pkgconfig
did the trick for me
Updating RMagick and Imagemagick is a painful expierence. I have updated the Imagemagick version on my mac (MacOS El Capitan Version 10.11.5) with homebrew for one project in Ruby 2.3 to 6.9.5-9
$ convert --version
Version: ImageMagick 6.9.5-9 Q16 x86_64 2016-09-09
Now an older project in Ruby 1.8.7 refuses to work with the error message "this installation of RMagick was configured with ImageMagick 6.8.9 but ImageMagick 6.9.5-9 is in use". Thus I uninstalled "rmagick", but it can not be installed again
$ gem install rmagick -v 2.16.0
Building native extensions. This could take a while...

Can't install RMagick 2.16.0. Can't find MagickWand.h.
And if it can not be installed, the whole application can not be started. I tried all the answers from here, and none of them works on MacOS :-( I reinstalled imagemagick and pkg-config with homebrew, and tried various version of RMagick without success. 2.16.0 is the latest version of RMagick currently.
MagicWand seems to be used in ImageMagick version > 6.9, and it can be found on the machine:
find /usr/local -name MagickWand.h
=> /usr/local/Cellar/imagemagick/6.9.5-9_1/include/ImageMagick-6/wand/MagickWand.h
find /usr/local -name MagickWand.pc
=> /usr/local/Cellar/imagemagick/6.9.5-9_1/lib/pkgconfig/MagickCore.pc
It does not work even if I specifiy the these paths during the gem install (same error as above) :-(
C_INCLUDE_PATH=/usr/local/Cellar/imagemagick/6.9.5-9_1/include/ImageMagick-6 PKG_CONFIG_PATH=/usr/local/lib/pkgconfig gem install rmagick
UPDATE:
The error only occurs for Ruby 1.8.7, it is possible to install RMagick for Ruby 2.0 and Ruby 2.3. Ruby 1.8.7 and ImageMagick 6.9.5 do not seem to be compatible.
Ruby 1.8.7 x
Ruby 2.0.0 ✓
Ruby 2.3.1 ✓
To solve the issue in Mac OSX Sierra, High Sierra, El Capitan, Mojave, Catalina, Big Sur, and Monterey (M1 chip), you can do the following:
brew unlink imagemagick
brew install imagemagick#6 && brew link imagemagick#6 --force
imagemagick#6 is keg-only, so you'll need to force linking.
I had this same issue with ImageMagick 7.0.4-4. The proper fix is to install imagemagick#6. I found https://github.com/Homebrew/homebrew-core/pull/8756 useful if you accidentally deleted your imagemagick#6 or never had it installed in the first place.
macOs Sierra:
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
First of all
unlink your installed imagemagick which was not properly installed in latest mac high sierra by using.
brew unlink imagemagick
then install latest imagemagic6 using below command
brew install imagemagick#6 && brew link imagemagick#6 --force
Then install gem rmagick using below command
gem install rmagick
It will work perfectly fine.
yah this one solves my issue:
MacOS X Sierra:
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
Many things have changed in ImageMagick 7 like this path: include/.../wand , and wand/MagickWand.h is hardwired in the rmagic gem at the moment. In my case it was not possible to update the gem since the project is rather old. So I ended up installing an older version of ImageMagic.
You can install the latest version from 6.x.x:
brew install https://raw.githubusercontent.com/Homebrew/homebrew-core/6f014f2b7f1f9e618fd5c0ae9c93befea671f8be/Formula/imagemagick.rb
You can also pin it for later usege:
brew pin imagemagick
Something changed with ImageMagick 7.0.4-4 for me. wand/MagickWand.h couldn't be found any more:
% brew unlink imagemagick && brew link imagemagick
Unlinking /usr/local/Cellar/imagemagick/7.0.4-4... 71 symlinks removed

RMagick depends on an outdated version of imagemagick, version 6.(see below) Homebrew offers this as a keg-only package, which you can install with:
brew install imagemagick#6
The build output will include a Caveats section (also available from brew info imagemagick#6 if you cleared the output):
==> Caveats
imagemagick#6 is keg-only, which means it was not symlinked into /usr/local,
because this is an alternate version of another formula.
If you need to have imagemagick#6 first in your PATH run:
echo 'export PATH="/usr/local/opt/imagemagick#6/bin:$PATH"' >> ~/.zshrc
For compilers to find imagemagick#6 you may need to set:
export LDFLAGS="-L/usr/local/opt/imagemagick#6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick#6/include"
For pkg-config to find imagemagick#6 you may need to set:
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig"
Rather than force-linking, which has the potential to cause problems with other software that does support newer versions of imagemagick, you can use the suggested exports to make the RMagick gem pick up the old version while it builds:
export LDFLAGS="-L/usr/local/opt/imagemagick#6/lib"
export CPPFLAGS="-I/usr/local/opt/imagemagick#6/include"
export PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig"
gem install rmagick
Go help contribute to the upgrade effort if you know Ruby and C!
Install imagemagick version 6 because version 7 is not compatible:
$ brew install imagemagick#6
Should not link --force the older version because this will change the binaries in your path and the good brew doctor will complain.
Reference the headers and libraries from version 6 that was installed when building the native extension of the gem:
$ PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick#6/6.9.10-14/lib/pkgconfig/ gem install rmagick -v '2.16.0'
Note: Worked for me without indicating the lib and include folder because the pkgconfig is responsible for this.
Note: 6.9.10-14 is the latest version of imagemagick#6, but feel free to change it if you need to use a different version
$ brew remove imagemagick && brew install imagemagick
$ brew uninstall pkg-config && brew install pkg-config
$ brew unlink pkg-config && brew link pkg-config
$ gem install rmagick
I don't have the reputation yet to leave this as a comment improving another answer, but #Evgeniy28's answer worked for me on Sierra only after also installing pkg-config, which doesn't come installed by default on a fresh Sierra machine.
So:
brew install pkg-config
brew uninstall imagemagick
brew install imagemagick#6
brew link imagemagick#6 --force
Success:
$ gem install rmagick

Here is how I solved (after lots of tries and fail) on macOS High Sierra 10.13.3 with Homebrew:
it seems that RMagick 2.16.0 is not compatible with the newest version of ImageMagick (Version 7): http://wordsandmagic.com/2017/09/01/RMagick-2-16-0-Error-MagickWand
I uninstalled imagemagick: brew uninstall imagemagick
Then I installed Imagemagick with this formula: https://gist.github.com/JagdeepSingh/4b03cbeab16cc0bc729bbc6d275402d3
gem install rmagick
If you have already installed an old version Imagemagick, this should work: https://stackoverflow.com/a/41674363
There's no need to link or unlink anything, following the instructions from the brew install script helps:
brew install imagemagick#6
LDFLAGS="-L/usr/local/opt/imagemagick#6/lib" CPPFLAGS="-I/usr/local/opt/imagemagick#6/include" PKG_CONFIG_PATH="/usr/local/opt/imagemagick#6/lib/pkgconfig" gem install rmagick

Voila, I'm now able to run this application locally.
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.
Something was severely wrong on my system, so badly that it was completely f*d up, but I was finally to able to install RMagick for Ruby 1.8.7 again after I installed
an older version of ImageMagick with Homebrew
a new Ruby version of 1.8.7
a new version of GCC
The installation of a new Ruby version with RVM rvm install 1.8.7 also installed a new GCC compiler: it removed an older GCC version 4.6 and installed GCC version 4.9. Apparently GCC was not able to find the right headers despite pkg-config.
First, you don't need to uninstall imagemagick if it has a 6.x installed, like shown below. You can see the current "main" is 7.0.7-8 but 6.9.1-10 is still there.
$ brew info imagemagick
imagemagick: stable 7.0.7-8 (bottled), HEAD
Tools and libraries to manipulate images in many formats
https://www.imagemagick.org/
/usr/local/Cellar/imagemagick/6.9.1-10 (1,450 files, 17.5MB)
Poured from bottle on 2015-07-26 at 09:10:58

Poured from bottle on 2017-08-21 at 14:44:16
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula
If you don't have an old 6.x version, then install imagemagick#6.
Second, do not force link imagemagick, especially not 6. EDIT: See ¹
You need to set PKG_CONFIG_PATH in addition to the --with-opt-* flags.
This works for me on High Sierra with aforementioned brew setup on Ruby 1.9.3-p551:
PKG_CONFIG_PATH=/usr/local/Cellar/imagemagick/6.9.1-10/lib/pkgconfig \
gem install rmagick -v '2.16.0' -- \
--with-opt-lib=/usr/local/Cellar/imagemagick/6.9.1-10/lib/ \
--with-opt-include=/usr/local/Cellar/imagemagick/6.9.1-10/include/ImageMagick-6/
Building ri docs fails, but those are inconsequential.
¹: Building works, the dylib path RMagick is searching is wrong though. Raised Issue #278 to clarify if this can be fixed. Otherwise manual symlinking of libMagickWand etc is necessary. Might still be safer to manually link the specific libraries than a brew link --force though.
I fully explain the installation process in ImageMagick install in centos .
anyway ...
after install Install Imagick & ImageMagick-devel & ImageMagick PHP library like below:
# yum install ImageMagick
# yum install ImageMagick-devel
# pecl install Imagick
go to /usr/include
cd /usr/include
Important: copy ImageMagick folder from "/usr/include" to "/usr/local/include" for ImageMagick find "MagickWand.h"
I tested this change on imagick-3.4.3(ImageMagick-7) and centos 6.5 and php56 and works perfectly ...
If you have already installed "ImageMagick" several times, first remove all of them and find "ImageMagick" & "imagick" folders and clean all of them and continue the installation process with this change.
Use the following command to find a file or folder:
find / -name 'ImageMagick*'
find / -name 'imagick*'
and continue your installation
before below lines don't forget:
go to "php.ini" find "disable_functions" and clean "proc_open,popen,proc_close" becuase make imagick needs these functions,
after complete installation you can add this functions to your "disable_functions" on "php.ini" file.
# phpize
# ./configure --with-php-config=/usr/local/php56/bin/php-config
...
Good luck...
For Ubuntu version > 12 and not using homebrew,
wget http://www.imagemagick.org/download/<required_imagemagick_version>
tar -xvf <path_to_your_downloaded_file>.tar.gz
If you are getting '7z' files instead of 'tar.gz' files in the wget link, then
7z x <path_to_your_downloaded_file>.7z
cd <path_to_your_downloaded_file>/
make
./configure
sudo make install
sudo ldconfig /usr/local/lib
Then you can resume your bundler for RMagick.

However, looking at nokogiri's mkmf.log, the following errors are shown:

I have xcode and it's command tools installed.
My ~/.bash_profile has 64bit compiling forced by: export ARCHFLAGS="-arch x86_64"
I have libxml2, libxslt, and libiconv installed via Homebrew, and each is linked.
I've tried installing all of these without the ARCHFLAG in .bash_profile.
I've also brew install apple-gcc42 and linked, as per how tos I've found.
I've tried installing nokogiri by passing paths to libxml2, libxslt, and libiconv in /usr/local/Cellar/, but the install still fails, with same errors as above.
I've wasted at least a day on this - just trying to get one Ruby gem installed. I'd really like to get back to actually developing.
Can anyone please help?
Setting NOKOGIRI_USE_SYSTEM_LIBRARIES=1 before actually installing the gem did the trick for me.
Summarising:
If previously installed, uninstall the gem:
$ gem uninstall nokogiri
Use Homebrew to install libxml2, libxslt and libiconv if needed:
$ brew install libxml2 libxslt libiconv
Install the gem specifying the paths to the libraries to be linked against:
$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"
Check if HomeBrew is installed correctly with the appropriate XCode command line tools.
brew doctor
You can also check via XCode > Preferences
With valid command line tools installed, I was able to resolve the nokogiri error encountered after the OSX Maverick upgrade.
Also found that some of the 'brew' packages were outdated after the OS X Mountain Lion to Maverick upgrade. (e.g. qt, postgresql)
Here's what worked for me:
If you haven't already done so, install the XCode developer tools: $ xcode-select --install
Use homebrew to install (or reinstall) libxml2, libxslt and libiconv: $ brew install libxml2 libxslt libiconv
Install nokogiri: gem install nokogiri -- --with-iconv-dir=/usr/local/opt/libiconv
I found the solution I needed in an unmerged pull request to update the Nokogiri tutorials. I recommend that if someone else encounters this issue and has exhausted the solutions here, check that pull request list to see if someone has submitted an update to the instructions on the Nokogiri tutorials page.
From github page
First, you should:
xcode-select --install
and then re-install nokogiri.
That worked for me while another suggestion didn't. Hope this helps someone else.
I want to install in my Fedora 12 based planet lab nodes one OMF RC:

After all this when i want to install:
gem install omf_rc --pre --no-ri --no-rdoc
It gives me the following error:

seems you need to install libxml, try:
sudo yum install -y gcc ruby-devel libxml2 libxml2-devel libxslt libxslt-devel
Also it needs the following installation:
sudo yum install -y git make gcc-c++
and
sudo yum groupinstall development-tools development-libs
