Hi,

Everything was working fine until I went to use ActiveMerchant.  
Have spent a few hours trying to figure this out with no success.

Here’s the error I’m getting

\*\* Starting Rails with development environment…  
Exiting  
/Library/Ruby/Gems/1.8/gems/activesupport-2.2.2/lib/active\_support/dependencies.rb:445:in  
`load\_missing\_constant’: uninitialized constant ActiveMerchant  
(NameError)

And in environment.rb I have

unless RAILS\_ENV == ‘production’  
PAYPAL\_ACCOUNT = ‘removed\_email\_address@domain.invalid’  
ActiveMerchant::Billing::Base.mode = :test  
else  
PAYPAL\_ACCOUNT = ‘removed\_email\_address@domain.invalid’  
end

Appreciate anyone kind enough to help me out. Can’t get my head around  
this and holding me back.

Cheers

Lee,

Do you need to have a require statement in environment.rb?

```
require 'active_merchant'

```
