运行报错，navigator is deprecated and has been removed。

打开当前目录，

npm install react-native-deprecated-custom-components --save

import {Navigator} from 'react-native-deprecated-custom-components';

修改后代码如下

'use strict';

  Text,
  View,
  TouchableHighlight,

        onPress={this.props.onPress}>
        <Text style={styles.buttonText}>{this.props.text}</Text>
      </TouchableHighlight>
    );
  }
}

  render() {
    return (
