RVM + Ruby 1.9.2 + Rmagick + Lion = System Works, RVM Doesn't

问题

I've installed Ruby 1.9.2 through RVM on a fresh install of OS X Lion. I have installed ghostscript and imagemagick through homebrew, and when running gem install rmagick using RVM, it fails. When using gem install rmagick on the system install of ruby, it works just fine.

This is the error that is produced:

What could be causing this? Any ideas on how to get RVM to see the imagemagick like it's should?

回答1:

The magick-installer script ( https://github.com/maddox/magick-installer ) does a fantastic job of installing ImageMagick on the mac. When I installed without using this script, the install would appear to succeed but the gem would never find the installation.

Using this script, I succeeded with installation where I had failed many times previously. Good luck :)
