NPM peer requirement errors - what to do?

I have a Metero application ( and when I start it, I get the following errors:

WARNING: npm peer requirements not installed:
react@15.3.1 installed, react@0.14.x needed
react-addons-update@15.3.1 installed, react-addons-update@0.14.x needed
react-addons-pure-render-mixin@15.3.1 installed, react-addons-pure-render-mixin@0.14.x needed

What is throwing this - other packages that are not compatible with 15.3.1?
If so, how do I find which other packages these are?
