Spark server instalation error

Hello,

I’m trying install the Spark-server on Raspberry and when I write this command: npm install I receive this error:

no compatible version found: node-oauth2-server@’>=1.5.2- <1.6.0-’

Attached below the screen with the error

Might want to take a look at this: http://gitbook.com/read/book/kennethlimcp/spark-local-cloud-on-raspberry-pi
