React-Native: Application has not been registered error

Question

I guess it is an error caused by not matching name of project and your registered component.

You have inited project with one name, i.e.

react-native init AwesomeApp

But in your index.ios.js file you register other component

AppRegistry.registerComponent('Bananas', () => Bananas);

When it must be

AppRegistry.registerComponent('AwesomeApp', () => Bananas);

If your component name does match, ensure you don’t have any other react-native/node process running in another terminal.
