After much digging, i believe that this problem is related to me not having any platforms added for phonegap to build from. This is missing from their documentation.
When i trying to add a platofrm phonegap
Running code
C:\var\www\sexdiaries.co.uk\sexdiaries>phonegap platform add andriod
[error] 'platform add andriod' is not a node C:\Users\Hutber\AppData\Roaming\npm\node_m
See 'node C:\Users\Hutber\AppData\Roaming\npm\node_modules\phonegap\bin\phonegap.js help'
