I'm trying to install Ruby on Rails and Redmine on Xampp on my Windows 7. I successfully installed ImageMagick and RMagick following this link:

http://rails.webintellix.com/2010/01/04/how-to-install-rmagick-imagemagick-on-windows/

But when I run bundle install i get the following error:

An error occurred while installing rmagick (2.13.3), and Bundler cannot
continue.
Make sure that `gem install rmagick -v '2.13.3'` succeeds before bundling.

So I tried instaling rmagick 2.13.3 using this command:

gem install rmagick --version=2.13.3 --platform=ruby -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include

But it also gave this error:

How can I fix this error?

UPDATE: I also tried this:

C:\Users\user1>gem install rmagick --version=2.13.3 --platform=ruby -- '--with-o
pt-lib="h:/ImageMagick-6.8.9-Q16/lib" --with-opt-include="h:/ImageMagick-6.8.9-Q
16/include"'

This is the result:

ERROR:  Could not find a valid gem 'rmagick' (= 2.13.3), here is why:
          Unable to download data from https://rubygems.org/ - no such name (htt
ps://rubygems.org/specs.4.8.gz)
ERROR:  Possible alternatives: rmagick

I still have no idea why I'm getting these errors!

Answer 1

Please follow steps in the following link your link seems to be missing dll linking

http://www.redmine.org/projects/redmine/wiki/HowTo_install_rmagick_gem_on_Windows

Answer 2

This did the trick for me:

$ gem install rmagick --platform=ruby -- --with-opt-lib=C:/RailsInstaller/ImageMagick-6.7.7-Q8/lib --with-opt-include=c
:/RailsInstaller/ImageMagick-6.7.7-Q8/include 

make sure to specify your own version of ImageMagick and the file path you installed it in & include the lib folder on the command
