Fail to install due to peerDependencie problem with object-assign package

// When I install the app using npm, I got the following errors:
npm ERR! Darwin 14.3.0
npm ERR! argv "/Users/georgejor/.nvm/versions/node/v0.12.5/bin/node" "/Users/georgejor/.nvm/versions/node/v0.12.5/bin/npm" "install" "react-foundation-apps" "--save"
npm ERR! node v0.12.5
npm ERR! npm v2.11.2
npm ERR! code EPEERINVALID

npm ERR! peerinvalid The package object-assign does not satisfy its siblings' peerDependencies requirements!

// The package require object-assign 2.x version but in my package.json:
"object-assign": "^3.0.0"

Please help with this issue, thanks!
