Issue with Paperclip / S3 in Rails 3.2.5 "cannot load such file - aws-sdk"

Uploading images worked fine, but when I tried to switch it to S3 it started giving an error. When trying to create a new image upload, I get the following error:

cannot load such file -- aws-sdk (You may need to install the aws-sdk gem)

      

        
        
        
      

    

Matching Gems:

gem 'rails', '3.2.5'
gem 'paperclip'
gem 'aws-sdk'

      

        
        
        
      

    

config / s3.yml:

development:
    bucket: bucketname
    access_key_id: #
    secret_access_key: #

test:
    bucket: bucketname
    access_key_id: #
    secret_access_key: #

      

        
        
        
      

    

image_upload.rb:

  has_attached_file :image,
    :styles => {
      :normal => "1680x6000",
      :result => "560x3000",
      :thumb => "140x500" },
    :path => ":attachment/:style/:normalized_file_name.:extension",
    :storage => :s3,
    :s3_credentials => "#{Rails.root}/config/s3.yml"

      

        
        
        
      

    

Things I've tried:

• install package
• Change aws-sdk version to 1.3.4
• gem install aws-sdk
• Changed the "Rails.root" s3_credentials part for a few different things.

Thanks for the help!
