Installing RMagick GEM
Several packages are required to get the RMagick GEM working. Using sudo or root access perform the following command:
apt-get install graphicsmagick imagemagick librmagick-ruby1.8 libmagick9-devAfter doing this you should be able to install the RMagick GEM:
gem install RMagickSome even recent installs of Debian/Ubuntu do not have the the latest version of Imagemagick. If it is less than version 6.3.0 then you will need to install an earlier version of RMagick using the following command:
gem install RMagick -v=1.15.12
