Hello, I am new to rails but have been having fun so far. Until now.  
I  
am sure this is just my inexperience but I have the RMagick gem (ruby  
gem  
for using imagemagick manipulation) installed on my machine that I  
would  
like to then use in my rails app. I first installed it and tried it  
out,  
and it didnt do anything for me, took me a while to realize I needed  
the  
windows RUBYOPT rubygems environment variable set. After that, I  
could  
finally call stuff like:

ruby myLittleTestProg.rb

which used a  
require ‘RMagick’  
and it would run fine.

So I think, I tested my little script out, I want to do it on rails  
and  
call it from my web app. I build a skeleton web app, and goto the  
config/environment.rb file and say:  
require ‘RMagick’

adding this line, kills the skeleton app, what ran fine with webrick  
now  
gives me a strange error that I wll post here. (and yes after  
changing the  
environment.rb file I did relaunch the server). I installed the  
flickr  
gem as well, and this runs fine, I can easily say in the  
environment.rbfile:  
require ‘flickr’  
and it works, it is just when I require ‘RMagick’ from that  
environment.rbfile in my rails app it crashes with this error in the  
index.rhtml:

I am looking for any suggestions, cause I am totally lost. Not sure  
why  
the RMagick include runs fine when I just use it from a ruby .rb file,  
but  
when I try to require it from my rails app, it doesnt work…this is  
locally  
using WEBrick (i tried my rails host online, and it seems that the  
require  
RMagick works there, I just need to get it working locally for  
development  
and testing purposes…)

Thanks for anyone with any help or suggestions…

-Shane  
error is as follows when require ‘RMagick’ is added to environment.rb  
of a  
skeleton rails app:

rmagick does not work with ruby 1.8.4 on windows. Replace any of these  
three  
with something else and it will work.

Windows XP  
ruby 1.8.4 (2005-12-24) [i386-mswin32]  
Rails 1.1.2  
RMagick-win32 (1.9.2)  
WEBrick 1.3.1

File\_column with RMagick works fine for me.  
I just tried it with skeleton app, that had require ‘RMagick’ in  
environment.rb and that worked ok too. Strange…
