React原生底部标签导航错误，来自expo模板的全新应用程序

Question

我刚刚用expo模板创建了一个新的应用程序，当执行时没有对代码进行任何更改，它会抛出以下错误

    C02SW0WD:Projects user$ expo init testTabApp
? Choose a template: 
  ----- Managed workflow -----
  blank                 a minimal app as clean as an empty canvas 
  blank (TypeScript)    same as blank but with TypeScript configuration 
***❯ tabs                  several example screens and tabs using react-navigation*** 
  ----- Bare workflow -----
  minimal               bare and minimal, just the essentials to get you started 
  minimal (TypeScript)  same as minimal but with TypeScript configuration 

作为附加测试，我创建了一个黑色项目，也使用expo init（空白-

1. 纱线添加@react navigation/native
2. 纱线添加@react导航/底部标签
3. 纱线添加天然屏幕
4. 纱线添加反应本地安全区域上下文

之后我创建了两个空屏幕，并修改了App.js以使用底部选项卡导航，如下所示：

import React from 'react';
import { Text, View } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import Chat from './screens/Chat';
import Home from './screens/Home';

const Tab = createBottomTabNavigator();

export default function App() {
  return (
    <NavigationContainer>
      <Tab.Navigator>
        <Tab.Screen name="Home" component={Home} />
        <Tab.Screen name="Chat" component={Chat} />
      </Tab.Navigator>
    </NavigationContainer>
  );
}

同样，关于“undefined不是函数（靠近“…Object.fromEntries…”的地方）的错误也是一样的

有什么想法吗？？

更新：问题在包内修复，更新到最新版本。https://github.com/react-navigation/react-navigation/commit/51f4d11fdf4bd2bb06f8cd4094f051816590e62c

方法对象。缺少fromEntries。添加纱线添加@babel/polyfill并更新您的。babelrc文件使用它：

{
    "presets": [
        "module:metro-react-native-babel-preset",
        "@babel/polyfill"
    ]
}

应该在那之后工作，更多的信息可以在网站上找到https://babeljs.io/docs/en/babel-polyfill
