I'm on windows and I downloaded and installed rmagick-win32 RMagick-2.12.0-ImageMagick-6.5.6-8-Q8 from here (http://rubyforge.org/frs/?group_id=12&release_id=42049) which I unzipped and installed using 'gem install rmagick'
When I try to run rails s, I get this error message
C:\Users\Me\Desktop\sample_app>rails s
←[31mCould not find gem 'rmagick (>= 0) x86-mingw32' in any of the gem sources l
isted in your Gemfile.←[0m
←[33mRun `bundle install` to install missing gems.←[0m
So I try to bundle install or bundle update then I get this (I took out the full list of gems to save space):
C:\Users\Me\Desktop\sample_app>bundle update

An error occured while installing rmagick (2.13.2), and Bundler cannot continue.
Make sure that `gem install rmagick -v '2.13.2'` succeeds before bundling.
Then I downloaded rmagick 2.13.2 and put it into the same folder and ran "gem install rmagick -v '2.13.2' but I'm getting a failed ERROR: Failed to build gem native extension again
I am trying to get 2.13.2 installed but I can't find any information on this. Anyone know if that's the issue and how this can be fixed?
