我收到這個錯誤[Sat Jul 25 2020 09:51:01.475]  ERROR    Error: The component for route 'ViewPayments' must be a React component. For example:import MyScreen from './MyScreen';...ViewPayments: MyScreen,}You can also use a navigator:import MyNavigator from './MyNavigator';...ViewPayments: MyNavigator,}[Sat Jul 25 2020 09:51:01.485]  ERROR    Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)[Sat Jul 25 2020 09:51:01.487]  ERROR    Invariant Violation: Module AppRegistry is not a registered callable module (calling runApplication)我想知道為什么這個錯誤是我的 App.js 代碼的樣子。ViewPayments 看起來像這樣：import React, { Component } from 'react';import { View, Text } from 'react-native';class ViewPayments extends Component {    static navigationOptions = {        title : "View Payments"        }  render() {    return (      <View>        <Text> ViewPayments </Text>      </View>    );  }}export default ViewPayments;一切似乎都很好，我什至把它當作屏幕，請問明顯有什么問題？我已經搜索并嘗試了我在互聯網上看到的幾種方法，但都無濟于事，在這種情況下似乎出了什么問題？當我編譯時，我將其作為返回錯誤
