node-sass v3.10.0 isn't supported on Windows with node 7:

https://github.com/sass/node-sass/releases/tag/v3.10.0

I got past this error by adding this to the dependencies in web-application\src\main\static\package.json:

"node-sass": "^3.11.1"

However, I then just get a further error trying to load the primeng module added by commit 9583eb so I don't know if the fix for node-sass is definitely the right one.

@katheris I think this is because the mvn clean doesn't clean out the old node_modules directory. I ran this on a fresh clone in a VM and it worked so I went back and tidied out my old node_modules and it now works on my Windows machine as well. I will add something to clean out the node_modules on a mvn clean so that we don't see this on future version updates...
