React Native - 错误:undefined不是对象(评估'require('NativeModules')。UIManager.AndroidDrawerLayout.Constants')

标签: ios react-native

根据官方启动指南here,我正在关注React Native的Hello World示例。在XCode上运行实际项目(未更改,未编辑文件)时,我在“死亡红屏”上收到以下错误。

Error: undefined is not an object (evaluating 'require('NativeModules').UIManager.AndroidDrawerLayout.Constants')

代码是股票标准默认代码,没有触及。

有什么想法吗?

谢谢!

/**

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
} = React;

var HelloWorld = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={styles.welcome}>
          Welcome to React Native!
        </Text>
        <Text style={styles.instructions}>
          To get started, edit index.ios.js
        </Text>
        <Text style={styles.instructions}>
          Press Cmd+R to reload,{'\n'}
          Cmd+D or shake for dev menu
        </Text>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    justifyContent: 'center',
    alignItems: 'center',
    backgroundColor: '#F5FCFF',
  },
  welcome: {
    fontSize: 20,
    textAlign: 'center',
    margin: 10,
  },
  instructions: {
    textAlign: 'center',
    color: '#333333',
    marginBottom: 5,
  },
});

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