Compilation errors

[MumblesNZ]

I can't seem to get this example to compile using npm run watch.

Below is the error log:

[15:09:35] can't resolve module E:/tmp/ionic-orm-test-master/node_modules/@angular/core/src/core_private_export.d.ts
from E:/tmp/ionic-orm-test-master/node_modules/@angular/core/src/core_private_export.d.ts
[15:09:35] Error: can't find symbol _core_private exported from module E:/tmp/ionic-orm-test-master/node_modules/@angular/core/src/core_private_export.d.ts
[15:09:35] ngc failed
[15:09:35] ionic-app-script task: "build"
[15:09:35] Error: Error

Any clues?
