Installing RMagick on Windows

Today while working on our project, I was facing trouble installing RMagick. It was - as expected, a windows issue, and while most guides on troubleshooting were old and out of date, a more recent Stack Overflow response (January 2014) more or less pointed out the issue was that Windows might not be supported in the more recent versions of ImageMagick with RMagick. So the solution was to use older versions when it worked, and it definitely solved my issue in installing it.

To sum up and quote the answer by Dany Khalife:

Uninstall ImageMagick and re-install a previous version that works with your Ruby setup.
This is what worked for me :

• Ruby 1.9.3
• Dev Kit 32-4.5.2
• ImageMagick 6.7.7 (i had a really hard time finding binary versions for legacy versions of ImageMagick so i guess this link will be handy for you: http://ftp.sunet.se/pub/multimedia/graphics/ImageMagick/binaries/)
• Rmagick 2.13.2

Keep in mind the version numbers! I'm running on Ruby 2.0.0 and it worked just fine. Be sure to use the following command, assuming ImageMagick was installed in C:/ :


gem install rmagick --version=2.13.2 --platform=ruby -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include 

And that's all there is to it. 'bundle install' should work just as well, too for the rails project. Hope this helps!
