Tried to build my very first app. Tried installing a plugin and faced this error issue:

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node_modules\chokidar\node_modules\fsevents): npm WARN notsup SKIPPING OPTIONAL DEPENDENCY: Unsupported platform for [email protected]: wanted {"os":"darwin","arch":"any"} (current: {"os":"win32","arch":"x64"}) npm WARN @ionic-native/[email protected] requires a peer of @ionic-native/core@^3.6.0 but none was installed. npm WARN @ionic-native/[email protected] requires a peer of rxjs@^5.0.1 but none was installed. npm WARN @ionic-native/[email protected] requires a peer of @ionic-native/core@^3.6.0 but none was installed. npm WARN @ionic-native/[email protected] requires a peer of rxjs@^5.0.1 but none was installed.

Wondering if anyone can help

Go to your package.json and ensure the following itens have these values

"dependencies": {
  "@angular/common": "4.0.2",
  "@angular/compiler": "4.0.2",
  "@angular/compiler-cli": "4.0.2",
  "@angular/core": "4.0.2",
  "@angular/forms": "4.0.2",
  "@angular/http": "4.0.2",
  "@angular/platform-browser": "4.0.2",
  "@angular/platform-browser-dynamic": "4.0.2",
  "@ionic-native/core": "^3.6.1",
  "@ionic-native/splash-screen": "3.4.2",
  "@ionic-native/status-bar": "3.4.2",
  "@ionic/storage": "2.0.1",
  "ionic-angular": "3.1.1",
  "ionicons": "3.0.0",
  "rxjs": "5.1.1",
  "sw-toolbox": "3.4.0",
  "zone.js": "^0.8.5"
},
"devDependencies": {
  "@ionic/app-scripts": "1.3.4",
  "typescript": "~2.2.1"
}

This is the needed to use the latest Ionic version, probably your @ionic-native/core and rxjs are not in this version, as the erros says it needs a higher version than the one you have.

Change your package.json, delete the node_modules folder of your project and then run npm install in it.

Hope this helps
