PrimeNG - npm WARN on dependencies - version update - node.js

Question

I have to update my PrimeNG version to the latest version which is: 1.0.0-rc.2
I used before the following package.json which is working fine:
{
"name": "primeng",
"version": "1.0.0-SNAPSHOT",
"scripts": {
"postinstall": "npm run typings install",
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",
"typings": "typings"
},
"license": "ISC",
"dependencies": {
"angular2": "2.0.0-beta.15",
"client-http": "0.0.7",
"systemjs": "0.19.25",
"es6-shim": "^0.35.0",
"reflect-metadata": "0.1.2",
"rxjs": "5.0.0-beta.2",
"zone.js": "0.6.10",
"primeng": "1.0.0-beta.3",
"primeui": "4.1.8"
},
"devDependencies": {
"concurrently": "^2.0.0",
"lite-server": "^2.1.0",
"typescript": "^1.8.9",
"typings": "^0.7.9"
}
}
Updating my PrimeNG version to the latest version, I also added some new dependencies. After update, my package.json looks like:
{
"name": "primeng",
"version": "1.0.0-rc.2",
"scripts": {
"postinstall": "npm run typings install",
"tsc": "tsc",
"tsc:w": "tsc -w",
"lite": "lite-server",
"start": "concurrently \"npm run tsc:w\" \"npm run lite\" ",
"typings": "typings"
},

},
"devDependencies": {
"concurrently": "^2.0.0",
"lite-server": "^2.1.0",
"typescript": "^1.8.9",
"typings": "^0.7.9"
}
}
After npm install I see some WARN-s in console.

How I can fix this problem? If I'm changing the library versions I receive other WARN-s conflicts
