[error][tid:com.facebook.react.JavaScript] Seems you're trying to access 'ReactNative.createClass' from the 'react-native' package. Perhaps you meant to access 'React.createClass' from the 'react' package instead?

For example, instead of:

  import React, { Component, View } from 'react-native';

You should now do:

  import React, { Component } from 'react';

  import { View } from 'react-native';

Check the release notes on how to upgrade your code - https://github.com/facebook/react-native/releases/tag/v0.25.1

请问老师：我通过require导入react-native的时候报错，使用以下方式的时候正常：

import React, { Component } from 'react';

import {

  AppRegistry,

  StyleSheet,

  View,

  PixelRatio,

  Text,

} from 'react-native';
