I did a search on the internet to try to find a way to get rid of  
message:  
C:0:Warning: require\_gem is obsolete. Use gem instead.

I found in an old archive, the following suggestion:  
"You can fix it in environment.rb. Find the ‘require\_gem’ lines and  
replace them with ‘gem’ "

When I do a search on my computer for this environment.rb file, I  
find several of them in various folders, but many do not show up as to  
their location. If I right click on them from the search window, (This  
is all in Windows XP), it has an open option, but no open with option.  
So I don’t know how to get to that environment.rb file. I can change  
all othe others but not sure if that will change these Ruby files.

Hi Rae,  
The environment.rb suggestion is only if you use Ruby on Rails. The  
warning is given by libraries you might use that are out of date, and  
use the recently deprecated require\_gem, you need to wwait for the  
maintainer to update the package

But if its not going to affect my ability to play with the program or  
run tutorials and such, I won’t worry about it.

C:\> dir \environment.rb /s

will find you all the files (with their locations!), and

C:\> edit \path\to\environment.rb

will let you edit them.

It won’t have any affect other than being annoying. An update to Instant  
Rails is coming soon.
