Yeah, looks like I also had a non windows version of the gem. Uninstalling and reinstalling the gem fixed it. Thanks.

It looks like maybe you're not using the Win32 version of the ImageScience gem. On my system it installed itself into the lib\ruby\gems\1.8\gems\image_science-1.1.3-x86-mswin32 folder of my Ruby installation, and it contains a file called Inline_ImageScience_aa58.so in the lib\inline folder of the gem (this is the precompiled bit that means you don't need cl).

It might be worth uninstalling all versions of the gem using gem uninstall and then re-downloading the pre-compiled gem and install as per step 3 of my instructions.

Looks like the problem is I don't have cl. But I am not sure why it is trying to compile anything. I have the FreeImage.dll in windows/system32.

Thanks for these easy instruction, but I hit a road block. I get this error when I do require 'image_science'. Any idea what I am screwing up? the only diffrence I can see is versions. I am rubyinline version 3.7.0 and Imagesceince 3.11.0. Thanks for any help.

Hi,

This is a wonderful article. I have followed the ways to install. But i'm getting error. Don't know where i'm going wrong. According to the 3rd step i've my ruby folder in the path D:\installation\ruby. So i've copied the gem to this folder and installed. Installation was successful. But when i run or when i test through irb require "image_science" it throwing error.

Bless you, bless you, god bless you, sir!

After pounding my head against rmagick for a long time (damn thing just refuses to work with rails for me), I said "screw it, I'll switch to Image Science" Your simple, clear 30 second instructions did the job and now attachment_fu us happy.

You rock.

Thanks Richard, I’ve updated the post. On my system I don’t need to explicitly require 'rubygems' because I used the one-click installer which sets the RUBYOPT environment variable.

Very helpful. Two minor edits:

gem install needs quotes, i.e. gem install "c:\Program Files\Ruby\image_science-1.1.3-i386-mswin32.gem"
test on irb only works if you've already done "require rubygems"

Thanks!

Insanely useful! Thank you very much!

There's always 'that' time when the only thing you have is a windows station, and when that time comes... this is an extremely helpful tutorial.

You should update the previous post (with the older method) and link to this one at the top. PageRank is much higher on the other one
