TypeError: Object #

I am attempting to install the SDK for Javascript using npm on my EC2 instance.

I have Node.js installed (v 0.10.33) and npm installed as well. I have been able to install other things such as Express.js without issue. However when trying to install the AWS SDK for Node I get the following error:

node.js:201
throw e; // process.nextTick error, or 'error' event on first tick
^
TypeError: Object #<Object> has no method 'tmpDir'

Does anyone have any idea what is causing this error or what I can do to fix it?
