ImageMagick / RMagick - Can't install RMagick 2.13.1. Can't find Magick-config
I am getting the following error when I try to run my dev console (MAC OS X / Snow Leopard). Does anyone know the solution?
/usr/local/bin/ruby extconf.rb
checking for Ruby version >= 1.8.5... yes
checking for gcc... yes
checking for Magick-config... no
Can't install RMagick 2.13.1. Can't find Magick-config in .:/usr/local/bin:/usr/local/sbin:/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin
*** extconf.rb failed ***
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.
I had a similar problem because I didn't include a library for a specific gem. Check your gems and see if they depend on a library which image gems always do.
config.gem gem_name, :lib => 'path_of_your_library'
I solved it by Installing libmagickwand-dev
apt-get install libmagickwand-dev
gem install rmagick
Before, I was getting following error (even after installing libmagick9-dev):
apt-get install libmagick9-dev
Reading package lists… Done
Building dependency tree
Reading state information… Done
Package libmagick9-dev is a virtual package provided by:
libmagickwand-dev 7:6.4.5.4.dfsg1-1ubuntu3.1
You should explicitly select one to install.
E: Package libmagick9-dev has no installation candidate
It seems that this problem is common in time to install the RMagick gem ... I had the same problem, and I've found the solution in this same site. Follow the link here.
Solution:
sudo apt-get install libmagick9-dev
