In chapter five of the book Build Your Own Ruby on Rails Applications,  
when I entered the rake db:migrate command in the Ruby console, I got  
the following message back:

Warning require\_gem is obsolete. Use gem instead.

What does this mean, and what should I do? Was the rake db:migrate  
command executed? If I want to update require\_gem, what do I need to do?

Thanks in advance.

This is not really a Rails problem, more an issue with the new gem  
package.  
You can safely ignore it, but if you want to get rid of the error then  
edit the config/boot.rb file and change line 29 (I think) from  
“require\_gem …” to just “gem”  
This has already been fixed in Rails development (edge)
