npm install breaks react-native app created with expo

I'm currently working with what is essentially the default stub code that is shipped when creating an app with expo (I've created a few different screens and done some styling). However, whenever I run any npm install command in my app's directory, the app becomes riddled with various dependency errors.

Terminal out put after npm install redux --save redux react-redux

Below is the output received in the ios simulator:

Unable to resolve module `react-redux/lib/utils/storeShape` from `../app/node_modules/@expo/ex-navigation/src/ExNavigationProvider.js`: Module does not exist in the module map or in these directories:

      ../app/node_modules/react-redux/lib/utils
    ,   ../app/node_modules/react-redux/lib/utils

When I attempt to remove and reinstall the node modules folder or reinstall npm, I receive multiple peerDependencies warning followed by install errors. I've tried installing various packages in clean projects and the results are similar. It seems as if others have had problems with node dependencies when working with expo.

It looks like you're using npm 2, which isn't supported since create-react-native-app depends in some way upon the flattening behavior of npm 3+ and Yarn.

React Native also best supports Node 6 and up, so I'd recommend upgrading Node as well.
