Ruby 1.9.2 how to install RMagick on Windows?

Question

I\'m currently upgrading an old rails app to use Rails 3 and Ruby 1.9.2, and RMagick is the last gem I need to install. However there doesn\'t seem to be any 1.9.2 download

Answer 1

After some attempts, this finally worked for me:

1. Install DevKit : https://github.com/oneclick/rubyinstaller/wiki/Development-Kit

2. Install ImageMagick (tick yes for headers in the installer) to a folder without spaces in its path (i used C:/ImageMagick)

3. Open up mingw (msys.bat in DevKit folder) -- and run gem install rmagick --platform=ruby -- --with-opt-lib=c:/ImageMagick/lib --with-opt-include=c:/ImageMagick/include (replace the two paths to account for your imagemagick path if needed)

Answer 2

Srividya's solution also works with ImageMagick-6.7.0-8-Q16-windows-dll and RMagick 2.13.1.
Make sure you are using 32-bit version of ImageMagick if this doesn't work for you on 64-bit version of Windows.
I did, and it works.

Answer 3

I just installed RMagick 2.13.1 successfully on Windows with Ruby v1.9.x !

Let me spill out the procedure, before I forget.

1. Install DevKit : https://github.com/oneclick/rubyinstaller/wiki/Development-Kit .
   
2. Install ImageMagick 6.6.x with windows installer with headers.
   NOTE:
   -Do not install ImageMagick in a path which has spaces in it.
   The default path C:/Program Files/... will not work.
   Install it at a simpler path.
   -- Remove any older installations of ImageMagick and RMagick

3. Set the paths in Environment Variables:

   set DFImageMagick environment variable to where ImageMagick is installed
   set PATH=%DFImageMagick%;%PATH% (if you don't already have it in PATH)
   set CPATH=%DFImageMagick%\include;%CPATH%
   set LIBRARY_PATH=%DFImageMagick%\lib;%LIBRARY_PATH%
   

4. Install RMagick gem : gem install rmagick
   This should say, Temporarily enhancing PATH to include DevKit... Building native extensions. This could take a while... After some time, Successfully installed rmagick 2.13.1

5. Verify installation:

   A. convert -version
   this should give the ImageMagick installation version
   B. gem list --local should list rmagick 2.13.1
   Alternative: in irb, try
   require 'rmagick'
   it should return 'true'
   

Oh, I do like installations which complete in 5 steps.

Hope this works for you and others.

Answer 4

I believe there are a few gotchas with RMagick and 1.9, as discussed in this thread at RubyInstaller group.

However, here you can find a post describing the steps.

Other tutorials can be found in our wiki

Hope that helps

• Installed rmagick in c:\rmagick.. folder

And tried the following command and it works:

gem install rmagick --platform=ruby -- --with-opt-lib=C:\ImageMagick-6.8.6-Q16\lib --with-opt-include=c:\ImageMagick-6.8.6-Q16\include

Answer 6

This did the trick for me using ruby 2.0:

$ 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
