problems running in browser and on android

[gregory-h]

After following the installation instructions (git clone, cd, npm install), running 'npm run browser:development' returns many missing module errors. I can resolve these by installing the missing modules, ie:

npm install react
npm install react-dom
npm install react-tap-event-plugin
npm install react-addons-perf (after first removing it from package.json)

After doing this much the app builds and I can open it in a browser, however there are many js warnings and several uncaught errors.

Running on android using:

npm run native:development,
npm run android:setup-port
react-native run-android

This starts the app in my emulator however it's mostly non functional - the ui shows only a few lines of text - 'To get started, edit index.android.js. Usage instructions not provided'. Is this as expected or ?

I'm using node 4.4.6, wondering if there is some other environmental requirement?
