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

Answer 2

The line in your Gemfile should be:

gem "rmagick", "~> 2.13.1"

Also, I would recommend using mini_magick instead as it takes less memory when processing:

gem "mini_magick", "~> 3.4"

Can I use carrierwave without rmagick?

Yes, but you will not be able to do image processing (resizing etc.). Uploading will work just fine.

Answer 3

Found a great answer from Stackoverflow. Worked for me. Can work for you.

cd /usr/local/Cellar/imagemagick/6.8.0-10/lib
ln -s libMagick++-Q16.7.dylib libMagick++.dylib
ln -s libMagickCore-Q16.7.dylib libMagickCore.dylib
ln -s libMagickWand-Q16.7.dylib libMagickWand.dylib

Answer 4

gem 'mini_magick', '~> 4.8'

bundle
