Here’s a very quick and easy way to install the RMagick Ruby gem to do some cool image manipulation and thumbnail management.

Install imagemagick & libraries

First install imagemagick on Ubuntu:

Check it’s installed:

Now install libmagick9-dev, making sure you choose the corresponding version for imagemagick *IF* asked (but you shouldn’t be):

Install Gem

Now the easy bit (and more stressful), installing the Ruby Gem:

After which you should see:

Include in your Ruby App

Now let’s use it, by adding to your controller/application_controller.rb:

Tada! Your ready to rock!

    What version of Ubuntu did you install on? I’m using Ubuntu 6.06.2, and apt-get only retrieves ImageMagick 6.2. The RMagick gem then complains that it needs ImageMagick 6.3.

    Hi Antun,

    I was running 7.10 I believe when I wrote this, I’ve not actually checked whether the instructions work on other versions (and also, not checked whether they still work!).

    I’ve been working a lot with Mono/.Net and not really looked at Ruby recently… may need to get back into it!

    Sorry, that comment is probably no help… :)
