Ionic 2 : Warn after "npm install" - node.js

Question

I use Ionic v2.1.8 and when I run the command "npm install" I have a lot of warn like this :
C:\xampp\htdocs\AppFineMobile>npm install
npm WARN #angular/compiler#2.4.8 requires a peer of #angular/core#2.4.8 but none was installed.

My package.json file :

}
I don't understand because I have these modules on my node_modules folder. And when I tried to install one of them, I keep the warn with another npm install.
I really don't understand and I don't know how to solve that

You just need to update all your angular packages to 2.4.8.Also your ionic-angular package is 2.2.0.
Change:
"#angular/common": "^2.4.8",
"#angular/compiler": "^2.4.8",
"#angular/compiler-cli": "^2.4.8",
"#angular/core": "^2.4.8",
"#angular/forms": "^2.4.8",
"#angular/http": "^2.4.8",
"#angular/platform-browser": "^2.4.8",
"#angular/platform-browser-dynamic": "^2.4.8",
"#angular/platform-server": "^2.4.8",
Also
"rxjs": "^5.0.1",
"zone.js" :"0.7.2"
Clear your node_modules folder in case of issues and do:
npm install
