Angular2 / Angular-cli: updating local project to Angular 4

I am trying to upgrade an angular-cli / angular 2 project to Angular 4. I updated my package.json with all the required angular4 modules and everything seems to be fine until I run the application. When I run the application, I get the following error:

Mistake:

Cannot read property "provide" undefined.

I've tried everything I can think of: I uninstalled node_modules and installed again with npm install, but still get the same error ... Any idea what might be wrong here / what I might try to solve? I am using angular-cli 1.0.0.rc-1

my package.json:
