Rmagick errors when running Rails S after upgradin

问题:

I updated my osx to Mavericks 10.9 from 10.7, and since then I have been having issues running 'rails s'.

The issue is with Rmagick, and I have tried almost every solution that I could find. Most people recommended reinstalling imagemagick through homebrew, and reinstalling rmagick gem, but that didn't work. I even uninstalled homebrew as a whole, and reinstalled it. I tried getting rid of gemfile.lock, and running bundle install again, but none of these worked.

Here is the error message I get when I try running the rails local server:

I had trouble with this as well on OS 10.9. I tried many things and this is what worked for me (after installing Xcode 5):

brew install libtool --universal
brew link libtool

Quick research just found the following with other users who also had success:

Edit: Another possibility is that you have a different version of RMagick than the gem is looking for (possibly from the reinstall). Your log shows your gem is looking for /usr/local/lib/libMagickCore.5.dylib which I am guessing it cannot find. Do

 ls /usr/local/lib/

and see if you can find that file. If not, a

gem pristine rmagick

may help if you haven't already tried it. In my case I have Core 6 in that folder and not 5.
