Error installing Rmagick on Mountain Lion

Question

I have seen other people with the same issue of installing RMagick on Mountain Lion However none of the suggested solutions have allowed me to successfully install rmagick.

Answer 1

What we did was the following:

cd /usr/local
git checkout 834ce4a Library/Formula/imagemagick.rb
brew install imagemagick

This will install Imagemagick 6.7.7-6

Answer 2

I know this is old, but I have been through a bunch of these responses and still wasn't able to get it to work. I found a random link in another language which actually solved the problem for me (http://sugiarto.webmuapp.com/Package_MagickCore_was_not_found_in_the_pkg_config_search_path). It looks like it was looking for PKG_CONFIG_PATH which was not set up.

What worked for me:

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig

Then make sure it worked:

find /usr -name 'MagickCore.pc'
/usr/local/Cellar/imagemagick/6.8.0-10/lib/pkgconfig/MagickCore.pc
/usr/local/lib/pkgconfig/MagickCore.pc

Then try installing rmagick again:

gem install rmagick
Building native extensions.  This could take a while...
Successfully installed rmagick-2.13.2

Success! Hope this helps anyone else still running into this issue.
