Question

我正在尝试将反应导航实施到我的应用程序中，但是只要我从react-navigation网站（链接：https://reactnavigation.org/docs/intro/basic-app）启动一个简单的示例应用程序，它就会失败并出现此错误：

TypeError: undefined is not a function (evaluating 'arr[typeof Symbol === 'function' ? Symbol.iterator : '@@iterator']()')

这是我的代码

import React from 'react';
import {
  AppRegistry,
  Text,
} from 'react-native';
import { StackNavigator } from 'react-navigation';

class HomeScreen extends React.Component {
  static navigationOptions = {
    title: 'Welcome',
  };
  render() {
    return <Text>Hello, Navigation!</Text>;
  }
}

export const SimpleApp = StackNavigator({
  Home: { screen: HomeScreen },
});

AppRegistry.registerComponent('navigation', () => SimpleApp);

我查看了其他查询，但似乎每个人都遇到导航功能问题，我甚至不打电话导航我只想用导航启动应用程序。你能帮我么？提前谢谢你：）
