Solo quería agregar geolocalización de fondo a mi aplicación Ionic 2 en ejecución:

 npm install --save @ionic-native/background-geolocation

me sale el error:

 > ├── @ionic-native/background-geolocation@3.5.0 ├── UNMET PEER > DEPENDENCY @ionic-native/core@^3.1.0 └── UNMET PEER DEPENDENCY > rxjs@5.0.0-beta.12 > > npm WARN @ionic-native/background-geolocation@3.5.0 requires a peer of > @ionic-native/core@^3.1.0 but none was installed. npm WARN > @ionic-native/background-geolocation@3.5.0 requires a peer of > rxjs@^5.0.1 but none was installed.

Mi paquete.json se ve así:

 { "name": "ionic-hello-world", "author": "Ionic Framework", "homepage": "http://ionicframework.com/", "private": true, "scripts": { "clean": "ionic-app-scripts clean", "build": "ionic-app-scripts build", "ionic:build": "ionic-app-scripts build", "ionic:serve": "ionic-app-scripts serve" }, "dependencies": { "@angular/common": "2.2.1", "@angular/compiler": "2.2.1", "@angular/compiler-cli": "2.2.1", "@angular/core": "2.2.1", "@angular/forms": "2.2.1", "@angular/http": "2.2.1", "@angular/platform-browser": "2.2.1", "@angular/platform-browser-dynamic": "2.2.1", "@angular/platform-server": "2.2.1", "@ionic-native/background-geolocation": "^3.5.0", "@ionic-native/core": "^3.5.0", "@ionic/cloud-angular": "^0.11.0", "@ionic/storage": "1.1.7", "ionic-angular": "2.0.1", "ionic-native": "2.4.1", "ionicons": "3.0.0", "rxjs": "5.0.0-beta.12", "sw-toolbox": "3.4.0", "zone.js": "0.6.26" }, "devDependencies": { "@ionic/app-scripts": "1.0.0", "typescript": "2.0.9" }, "cordovaPlugins": [ "cordova-plugin-whitelist", "cordova-plugin-console", "cordova-plugin-statusbar", "cordova-plugin-device", "cordova-plugin-splashscreen", "ionic-plugin-keyboard" ], "cordovaPlatforms": [ "ios", { "platform": "ios", "version": "", "locator": "ios" } ], "description": "App2: An Ionic project" }

¿Cómo puedo arreglar esto?
