bash - $GEM_PATH 通常设置在哪里？

Question

$GEM_PATH 设置在哪里？

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

但这不是我期望的地方，例如

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

编辑

这里也没有:

vim config/environment.rb 

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

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