Cannot install RMagic gem

Question

I'd like to install RMagic gem, I got “Can't find Magick-config” so I installed

 $ sudo apt-get install libmagickwand-dev

but now I get following output:

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/usr/local/rvm/rubies/ruby-2.1.5/bin/ruby -r ./siteconf20150526-12203-xr9xf7.rb extconf.rb checking for Ruby version >= 1.8.5... yes checking for gcc... yes checking for Magick-config... yes checking for ImageMagick version >= 6.4.9... * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers.

extconf failed, exit code 1

Gem files will remain installed in /usr/local/rvm/gems/ruby-2.1.5@rails4/gems/rmagick-2.13.4 for inspection. Results logged to /usr/local/rvm/gems/ruby-2.1.5@rails4/extensions/x86_64-linux/2.1.0/rmagick-2.13.4/gem_make.out

Could someone help me solve it?

Answer 1

After trying the above solutions and still not working .. i tried this one sudo apt-get install graphicsmagick-libmagick-dev-compat did the trick for me

Answer 2

Make sure you install ImageMagick. Usually, not having the right dependencies is the culprit.

Answer 3

Look at where it fails (which was hard to work out because your newlines got swallowed somewhere):

checking for ImageMagick version >= 6.4.9... * extconf.rb failed *

This check didn't get a "yes", which suggests that the libmagickwand-dev package you installed did not provide a version of ImageMagic >= 6.4.9 which is apparently the version that the rmagick gem version 2.13.4 requires.

Either get a newer ImageMagick or an older rmagick gem.
