Rails - cannot run rake command because of "libMagickCore.5.dylib"

Question

When I run run rake db:create, I get this error statement:

rake aborted!

I spent whole afternoon with looking for an issue and how to fix it, but without success.

The problematic part is here:

  Referenced from: /usr/local/opt/imagemagick/lib/libMagickCore.5.dylib
  Reason: Incompatible library version: libMagickCore.5.dylib requires version 13.0.0 or later, but libjpeg.8.dylib provides version 12.0.0 - /Users/adam/.rvm/gems/ruby-1.9.3-p327/gems/rmagick-2.13.1/lib/RMagick2.bundle

How can I upgrade libMagickCore.5.dylib on OS X Lion?

Thank you in advance

EDIT: After reinstalling imagemagick I ran rake db:create and got:

Answer 1

Try gem pristine rmagick from the command-line.

Answer 2

I had a similar problem in the past and simply ran a software update on the operating system and on the developer tools.

If that doesn't solve the problem, you can also try removing and reinstalling imagemagic with homebrew by running:

brew update
brew remove imagemagick
brew install imagemagick
