React Native : React Native Undefined Is Not An Object (evaluating 'this._lazycallablemodules

I'm new to try react native android app development, and got this error. This is my index.android.js import React from 'react'; import { StyleSheet, Text, View } from 'react-nativ

Solution 1:

Found this issue on react-native's repo： https://github.com/facebook/react-native/issues/14933#issuecomment-314150944， try change your babel-preset-react-native in package.json to 2.0.0 and then run npm install and do watchman watch-del-all, then try start running the project again.

Not sure if this would be the issue, but try it out: change import React from 'react'; into import React, { Component } from 'react';

And then change export default class App extends React.Component into export default class App extends Component
