通常设置$ GEM_PATH在哪里？

Question

$ GEM_PATH在哪里设置？

它显然正在设置,如下所示:

echo $GEM_PATH
/Users/snowcrash/.rvm/gems/ruby-1.9.2-p318:/Users/snowcrash/.rvm/gems/ruby-1.9.2-p318@global

但它不是我所期望的,例如

[app (master)]$ grep GEM_PATH ~/.bash_profile
[app (master)]$ grep GEM_PATH ~/.bashrc
[app (master)]$ 

编辑

它也不在这里:

vim config/environment.rb 

# Load the rails application
require File.expand_path('../application', __FILE__)

# Initialize the rails application
Accounts::Application.initialize!
