undefined is not an function (evaluating React.createClass)

How can i solve this?

Answer 1

Import React from react package, and the rest from react-native , like:

import React from 'react';
import {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  ToolbarAndroid
} from 'react-native';

Example: https://rnplay.org/apps/nKECFw

Here first run the command as

brew install node

And then

react-native start --reset-cache
react-native run-androd
