Compatible warning?

While installing angular2-logger i get this WARN-s:

npm WARN angular2-logger@0.5.0 requires a peer of @angular/common@2.0.0 but none was installed.
npm WARN angular2-logger@0.5.0 requires a peer of @angular/compiler@2.0.0 but none was installed.
npm WARN angular2-logger@0.5.0 requires a peer of @angular/core@2.0.0 but none was installed.
npm WARN angular2-logger@0.5.0 requires a peer of @angular/platform-browser@2.0.0 but none was installed.

Im using:
"@angular/common": "~2.1.0",
"@angular/compiler": "~2.1.0",
"@angular/core": "~2.1.0",
"@angular/platform-browser": "~2.1.0",

After installing logger actually works!

I think this is related to #74 . I'll merge it soon.
I was hoping greenkeeper would catch it but for some reason it isn't.
