Could not find gem 'rmagick v 2.13.1 (>= 0) x86-mingw32' in the gems available o

Hi I am getting message when I run bundle install below is my gemsfile

source 'https://rubygems.org'

gem 'rails', '3.2.6'

# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'

gem 'sqlite3'

gem 'carrierwave'
gem 'rmagick v 2.13.1'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
 gem 'sass-rails',    '~> 3.2.3'
gem 'coffee-rails',  '~> 3.2.1'

# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platforms => :ruby

gem 'uglifier', '>= 1.0.3'
end

gem 'jquery-rails'

# To use ActiveModel has_secure_password
 gem 'bcrypt-ruby', '~> 3.0.0'

# To use Jbuilder templates for JSON
 # gem 'jbuilder'

# Use unicorn as the app server
# gem 'unicorn'

# Deploy with Capistrano
# gem 'capistrano'

 # To use debugger

gem 'will_paginate','~> 3.0'

Is there another way to install the the RMagick gem in Rails 3? I installed carrierwave and need to use rmagick with it. Can I use carrierwave without rmagick?

Answer 1

You need to alter your Gemfile a little bit.

gem 'rmagick', '2.13.1'

You also need to install imagemagick on your system. rmagick requires imagemagick

You can install via yum, apt-get or whatever package manager your OS uses.

One note is that installing imagemagick on OSX is a little tricky. I recommend using homebrew

brew install -f imagemagick --disable-openmp
