Is 'require "rubygems" necessory?

Ruby
1

I create a sample app in padrino. orm is sequel and db is sqlite3 as
default. When I rake sq:migrate:auto, it will failed because of database
is not loaded. So I run the irb, and in irb require ‘sqlite3’ failed.
But It will be ok if I require ‘rubygems’ before require ‘sqlite3’. Is
'require “rubygems” necessory?

It is if you are using ruby 1.8.x. Since ruby 1.9 the gem directories
are part
of the path by default, so it isn’t needed any more.

You are right. All the gems include sequel and padrino is lastest except
the ruby is 1.8.7. Must I install the ruby 1.9 to develop padrino app?

gem env:
H:\study\fybjy\myoa>gem env

No, you just have to require rubygems before using them.
