I’m having a tough time with the upgrade to RC.0 and am hoping you can help. Basically I’m getting UNMET PEER DEPENDENCY and ultimately cannot start the app.

$ npm install  
ionic-hello-world@ C:\projects\slo  
±- UNMET PEER DEPENDENCY @angular/common@2.0.1  
±- UNMET PEER DEPENDENCY @angular/compiler@2.0.1  
±- UNMET PEER DEPENDENCY @angular/core@2.0.1  
±- UNMET PEER DEPENDENCY @angular/forms@2.0.1  
±- @angular/router@3.0.1  
`-- @angular/upgrade@2.0.1

npm WARN optional SKIPPING OPTIONAL DEPENDENCY: fsevents@^1.0.0 (node\_modules\chokidar\node\_modules\fsevents):

This is my dependencies block of my package.json:  
“dependencies”: {  
"@angular/common": “~2.0.1”,  
"@angular/compiler": “~2.0.1”,  
"@angular/core": “~2.0.1”,  
"@angular/forms": “~2.0.1”,  
"@angular/http": “~2.0.1”,  
"@angular/platform-browser": “~2.0.1”,  
"@angular/platform-browser-dynamic": “~2.0.1”,  
"@angular/router": “~3.0.1”,  
"@angular/upgrade": “~2.0.1”,  
"@ionic/storage": “1.0.3”,  
“chart.js”: “^2.3.0”,  
“ionic-angular”: “^2.0.0-rc.0”,  
“ionic-native”: “^2.0.3”,  
“ionicons”: “^3.0.0”,  
“ng2-charts”: “^1.3.0”  
},

Any guidance is greatly appreciated! I’ve also tried changing the angular 2 versions to 2.0.0 and get the same error.
