Installing rmagick gem on ubuntu 14.04 - ruby-on-rails

Question

I'm trying to deploy an app on OpsWorks, but there are problems with installing rmagick gem. I have the following OS packages:
libmagickwand-dev imagemagick libmagickcore-dev
Below is the log file with errors during deployment:
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes

Can't install RMagick 0.0.0. Can't find Magick-config in /usr/local/bin:/usr/bin:/bin:/usr/local/games:/usr/games

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.

An error occurred while installing rmagick (2.13.3), and Bundler cannot

Make sure that `gem install rmagick -v '2.13.3'` succeeds before bundling.

Answer 1

In your shell, run the following command:
apt-get install libmagickwand-dev

Answer 2

I had the same problem after upgrading ubuntu to 15.05, some how the Magick-config file is no longer in my PATH.
To fix this I first found the location of Magick-config
sudo find / -name "Magick-config"
which was /usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/Magick-config then I added it to the path. Bundle succeeded afterwards.

Answer 3

sudo apt-get install libmagickwand5 libmagickwand-dev
gem install rmagick -v 2.13.3

Answer 4

Install Imagemagick-dev libraries
Ubuntu systems: sudo apt-get install libmagickwand-dev
RHEL systems: yum install ImageMagick-devel
Mac: brew install imagemagick

Answer 5

In Ubuntu 14.04 I also needed to install the libgmp-dev library to get working the newer rmagick 2.15.4 version:
sudo apt-get install libgmp-dev
Hope this helps!

Answer 6

to fix it permanently we could just do:
ln -s /usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/Magick-config /usr/bin/Magick-config

Answer 7

First of all we need to search configuration
sudo find / -name "Magick-config"
You will get output something like this:
/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/Magick-config
Now you just need to setup bin location in your environment by using this:
PATH=$PATH:/usr/lib/x86_64-linux-gnu/ImageMagick-6.8.9/bin-Q16/
Don't forget to remove Magick-config from end of line.
