Hi, something does not work? I have the same warning, but app runs fine.

[mangopop]

Just done some testing and the app does seem to run ok.

I think this is a spurious message because of unfixed messiness in the various underlying libraries. Once the versions stabilize (i.e.. the various libraries are updated and reconciled to agree on what TypeScript version they want), these messages should go away. In the meantime, I've been using TypeScript 2.0.0 and getting good results, while ignoring messages that complain about an UNMET PEER DEPENDENCY for something that is sitting right there...

Peer dependency warning will be around for a bit while the ecosystem adapts to the new Typescript and Node versions.

They should be warnings however, not errors - try updating to NPM3 and they should be listed as warnings.

I have npm3 but these show as ERRors not warnings:

➜  ng-challenge git:(master) ✗ npm --version
3.10.6
➜  ng-challenge git:(master) ✗ npm list typescript
ng-challenge@0.0.0 /Users/sci-lmw1/Documents/dev/ng-challenge
├─┬ angular-cli@1.0.0-beta.11-webpack.2
│ └─┬ typedoc@0.4.5
│   └── typescript@1.8.10 
└── UNMET PEER DEPENDENCY typescript@2.0.0

npm ERR! peer dep missing: typescript@^1.9.0-dev, required by @angular/tsc-wrapped@0.2.2

Am I missing something, or do I still just ignore this?
