When building native Ruby gems  sometimes you ll get an error containing   ruby extconf rb   This is often caused by missing development libraries for the gem you re installing  or even Ruby itself   Do you have apt installed on your machine  If not  I d recommend installing it  because it s a quick and easy way to get a lot of development libraries   If you see people suggest installing  libmagick9-dev   that s an apt package that you d install with     sudo apt-get install libmagickwand-dev imagemagick   or on centOs     yum install ImageMagick-devel   On Mac OS  you can use Homebrew     brew install imagemagick

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

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

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

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

User · Answer

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   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     Password      Reading Package Lists    Done     Building Dependency Tree    Done     E  Couldn t find package 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

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

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  For more details  https   askubuntu com a 230958 6506

Important   sudo apt-get install libmagick  4 libmagick  -dev   works on linux mint 13 after making updates   sudo apt-get update

User · Answer

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

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

In some OS you need to use new libraries  libmagick  4 libmagick  -dev  You can use   sudo apt-get install libmagick  4 libmagick  -dev

User · Answer

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

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
