Does not satisfy peer dependencies

When running 

`npm install react-loopback`

I get the following: 

```
npm ERR! peerinvalid The package react@15.0.1 does not satisfy its siblings' peerDependencies requirements!
npm ERR! peerinvalid Peer react-dom@15.0.1 wants react@^15.0.1
npm ERR! peerinvalid Peer react-loopback@0.4.0 wants react@^0.14.1
```

and react-loopback does not install.
