angular2, typescript peer invalid, can't import modules

Question

I have two issues, propably, its depend each other :

i can't reguire/import [email protected]
typescript works but i see error

by command npm list:

├── [email protected] extraneous
├── [email protected]
├── [email protected] peer invalid
├── [email protected]
└── [email protected]

npm ERR! extraneous: [email protected] C:\Users\AxOn\Documents\projects\NODETS+ANGULAR2\public\node_modules\sass
npm ERR! peer invalid: [email protected] C:\Users\AxOn\Documents\projects\NODETS+ANGULAR2\public\node_modules\typescript

propably, because of [email protected] peer invalid i can't see module:

import { sass } from 'sass'; //error

after, sass is absent in packege.json

"devDependencies": {
    "concurrently": "^2.2.0",
    "lite-server": "^2.2.2",
    "typescript": "^1.8.10",
    "typings":"^1.3.2"
  }

Setting typescript's version to 2.0.2 helped to fix the typescript error in my case.

"devDependencies": {
    // other dependecies ...
    "typescript": "^2.0.2",
    // other dependecies ...
  }

May be this error is the result of an upgrade of the angular-compiler and it's dependencies while forgetting to upgrade the documentation.
