@dinesh100ni I had exactly the same issue as you. Full disclaimer I'm not 100% sure what's going on here, and what was going on behind the scenes, but I think it was related to the libraries that had been installed by GIMP 2.9.9 developer edition but the solution was to use sudo aptitude install libmagickwand-6.q16-dev. (you might have to sudo apt-get install aptitude). For me it was the second suggestion (reached by hitting "n") that worked.. the first one didn't actually do anything. The second one downgraded some of the GIMP 2.9.9 files which I don't care about as I'm using the flatpak installed GIMP 2.10. After that I could install libmagickwand-dev

Thanks Its Working

Just ran into a similar problem trying to install it on Arch Linux:

checking for brew... yes
checking for Ruby version >= 2.3.0... yes
checking for pkg-config... yes
Package MagickCore was not found in the pkg-config search path.
Perhaps you should add the directory containing `MagickCore.pc'
to the PKG_CONFIG_PATH environment variable
No package 'MagickCore' found


ERROR: Can't install RMagick 4.2.4.
Can't find the ImageMagick library or one of the dependent libraries.
Check the mkmf.log file for more detailed information.

This was the solution:

export PKG_CONFIG_PATH=/usr/lib/pkgconfig
gem install rmagick

I got the path from here: https://archlinux.org/packages/extra/x86_64/imagemagick/files/
