无法解决"./SafeAreaContext“

Question

我最近设置了react-native project with expo，后来添加了@react-navigation包。

似乎这还不够，因为NavigationContainer渲染抱怨SafeAreaContext

我试图用expo install react-native-safe-area-context ...安装所需的软件包，但它没有解决这个问题。

删除node_modules && npm install可能会有帮助，但也不起作用。

There were related questions to this issue，but they didn't provide much help

我会感谢你的帮助。。

这里是我在android仿真器中得到的

终端

Unable to resolve "./SafeAreaContext" from "node_modules\react-native-safe-area-context\src\index.tsx"
Failed building JavaScript bundle.

App.tsx

import React, { useState } from 'react';
import { AppLoading } from 'expo'
import { View, Text } from 'react-native';
import { NavigationContainer } from '@react-navigation/native';
import { createBottomTabNavigator } from '@react-navigation/bottom-tabs';
import { createStackNavigator } from '@react-navigation/stack';

function Test() {
  return (
    <View
      style={{ flex: 1, justifyContent: 'space-between', alignItems: 'center' }}
    >
      <Text>Test</Text>
    </View>
  );
}
const Stack = createStackNavigator();
const Tab = createBottomTabNavigator();

export default function App() {
 const [loaded, setLoaded] = useState(false);


  if(!loaded) {
    return <AppLoading
      startAsync={() => Promise.resolve()}
      onFinish={() => setLoaded(true)}/>
  }

  return <NavigationContainer>
    </NavigationContainer>
}

Answer 1

Look like cleaning expo cache helped

expo r -c

expo r --help

Usage: start|r [options] [project-dir]
Starts or restarts a local server for your app and gives you a URL to it

 Options:
    -c, --clear           Clear the Metro bundler cache
   ....

expo --version
3.21.3

Answer 2

安装以下两个，

npm install --save @react-native-community/masked-view

npm install react-native-safe-area-context

这是我的工作
