[ruby-on-rails-3] rmagick gem install "Can't find Magick-config"

I get the error shown below when attempting to install the rmagick gem. I am on Snowleopard 10.6 using RVM, Ruby 1.9.2-head and Rails 3.05. Responses to similar questions recommended installing ImageMagick, which I successfully did. Other suggested installing the "libmagick9-dev library", however, I can not figure out how to do this.

I'm a new developer, and any assistance or directions to an existing explanation or resource is greatly appreciated. Thanks!

UPDATE If you're a Mac/OS X user I would HIGHLY recommend using Homebrew as your package installer/manager. You can find it HERE. Since originally asking this question I have removed all my prior installs of things like rmagick and imagemagick, and reinstalled them using Homebrew. Super easy with a huge catalog of packages, and updates/uninstalls are a cinch as well!

Important:

sudo apt-get install libmagick++4 libmagick++-dev

works on linux mint 13 after making updates:

sudo apt-get update

Things change...maybe this will help someone else:

sudo apt-get install libmagick9-dev used to work. But with a later version of imagemagick I needed:

sudo apt-get install graphicsmagick-libmagick-dev-compat libmagickcore-dev libmagickwand-dev

I finally got it working by utilizing a script for ImageMagick installation on github.

magick-installer ( https://github.com/maddox/magick-installer )

It made a fresh install of ImageMagick, and the RMagick 2.12.2 gem then installed perfectly via bundler.

Thanks to Hulihan Applications for confirming that it was most likely a missing library. I tried the suggestion of using apt-get by installing the package downloader from Fink Project. I ran the following command in terminal, but it couldn't find the libmagick9-dev libary.

$ sudo apt-get install libmagick9-dev

I need to bone up on my UNIX command line skills. The original copy of ImageMagick that I installed from source is still on the machine, but I don't know where exactly or how to remove it. So much to learn...!

Try

1) apt-get install libmagickwand-dev

2) gem install rmagick

On ubuntu, you also have to install imagemagick and libmagickcore-dev like this :

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

Everything is written in the doc.

Remember to ckeck the archive Gemfile.lock after the instalation. Remove this archive and execute bundle again. It works for me in linux :D

In some OS you need to use new libraries: libmagick++4 libmagick++-dev

You can use:

sudo apt-get install libmagick++4 libmagick++-dev

execute this in terminal

  sudo apt-get install libmagickcore-dev libmagickwand-dev

if its not work than

sudo ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/Magick-config /usr/local/bin/Magick-config

for reference

After much digging, I fixed this on debian 8.3 using information here: https://www.bountysource.com/issues/18142073-can-t-install-gem-on-ubuntu-15-04 Specifically:

sudo apt-get purge graphicsmagick graphicsmagick-dbg imagemagick-common imagemagick imagemagick-6.q16 libmagickcore-6-headers libmagickwand-dev
sudo apt-get autoremove
sudo apt-get install imagemagick libmagickwand-dev
gem install rmagick

For CentOS 5/6 this is what worked for me

yum remove ImageMagick
yum install tcl-devel libpng-devel libjpeg-devel ghostscript-devel bzip2-devel freetype-devel libtiff-devel
mkdir /root/imagemagick
cd /root/imagemagick
wget ftp://ftp.imagemagick.org/pub/ImageMagick/ImageMagick.tar.gz
tar xzvf ImageMagick.tar.gz
cd ImageMagick-*
./configure --prefix=/usr/ --with-bzlib=yes --with-fontconfig=yes --with-freetype=yes --with-gslib=yes --with-gvc=yes --with-jpeg=yes --with-jp2=yes --with-png=yes --with-tiff=yes
make
make install

For 64 bit do this

cd /usr/lib64
ln -s ../lib/libMagickCore.so.3 libMagickCore.so.3 
ln -s ../lib/libMagickWand.so.3 libMagickWand.so.3

Add the missing dependencies

yum install ImageMagick-devel

Then finally rmagick

gem install rmagick

If you need to start fresh remove other installs first with

cd /root/imagemagick/ImageMagick-*
make uninstall

The new correct way is to install libmagickwand-dev:

sudo apt-get install libmagickwand-dev

Then you should be able to install rmagick no problem.

in ubuntu 15.10

sudo apt-get install graphicsmagick-libmagick-dev-compat

did the trick for me

Ubuntu 15.10

Note that if you try to install this gem in ubuntu 15.10, then error can happened:

Can't install RMagick 2.13.1. Can't find Magick-config in ...

All you need is preload PATH variable with additional path to ImageMagick lib.

PATH="/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16:$PATH"

then run gem install rmagick

source of solution

On Mac OS X sudo port install ImageMagick turned out to work fine to fix the gem install rmagick problem . I just didn't know that it worked fine because rvm during installation blew away my .bash_profile contents which included MacPort's addition of /opt/local/bin to PATH. I put back /opt/local/bin into PATH in my .bash_profile and then my gem install rmagick then succeeded.

For those who don't want to do the build-from-source approach of the (otherwise excellent installer script by John Maddox, the following worked for me when installing on CentOS 6.2. (Adjust your package manager as necessary).

yum install -y {libwmf,lcms,ghostscript,ImageMagick}{,-devel}
gem install rmagick

Again, this is mainly of interest if you use your distro's package manager and would really prefer to keep it sane.

I had to specify version 6

brew install imagemagick@6
brew link --overwrite --force imagemagick@6

What I did to fix the problem on Ubuntu was

$ sudo apt-get install libmagickwand-dev
$ sudo apt-get install ImageMagick

I had this problem when I had already installed ImageMagick with macports. I ran

    port contents ImageMagick | grep config

To find where the config file had been stored and then ran

    PATH=(insert your path here):${PATH} bundle

to install the gem using bundler. From now on, if you run a command that needs to reference ImageMagick, you can prefix it with that command. For example I had a migration that referenced it, so I ran

    PATH=/opt/local/bin/:${PATH} rake db:migrate

opt/local/bin/ is the path where my config file was stored.

Can't install RMagick 2.13.2. in ubuntu 17.10

My decision

 - sudo apt-get purge imagemagick libmagickcore-dev libmagickwand-dev
 - sudo apt-get autoremove
 - sudo rm /usr/bin/Magick-config

 - sudo apt-get install imagemagick libmagickwand-dev

Version is required to correctly specify the path to the configuration

• cd /usr/lib/x86_64-linux-gnu
• View version ImageMagick, my version ImageMagick - 6.9.7.
• cd ImageMagick-6.9.7/
• ls
• look at the name of the directory bin-q16 or bin-Q16

Creating a link to the config

sudo ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-version/bin-directory/Magick-config /usr/bin/Magick-config

Creating for my version ImageMagick

 - sudo ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-6.9.7/bin-q16/Magick-config /usr/bin/Magick-config
 - bundle

Installing rmagick gem in Ubuntu

sudo aptitude Install Imagemagick and GraphicsMagick(If not aptitude go & install in s/w center) sudo aptitude Install libmagickcore-dev libmagickwand-dev gem install rmagick -v 2.13.1

If you get an error similar like:

The following packages have unmet dependencies:
 libmagickwand-dev : Depends: libmagickcore4-extra (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed
                     Depends: libmagickcore-dev (= 8:6.6.9.7-5ubuntu3.2) but it is not going to be installed

You might want to start with this package: sudo apt-get install libgvc5

I ran this issue twice on different machine, first time it was resolved by installing the libmagick9-dev

sudo apt-get install libmagick9-dev

and second time i have to install the following libraries.

sudo apt-get install libmagick++4 libmagick++-dev

Ubuntu:

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

CentOS:

yum remove ImageMagick
gem uninstall rmagick
yum install ImageMagick ImageMagick-devel ImageMagick-last-libs ImageMagick-c++ ImageMagick-c++-devel
gem install rmagick

MacOS:

download and install http://xquartz.macosforge.org/trac/wiki/X112.7.2

after:

brew uninstall imagemagick
brew link xz jpeg freetype    
brew install imagemagick
brew link --overwrite imagemagick
gem install rmagick

imagemagick@6 works for me!

brew unlink imagemagick
brew install imagemagick@6 && brew link imagemagick@6 --force
