Question

我更新了我的Android项目react-navigation was 3.x，移至5.x，决定实施必要的更改，但它不起作用，从react-navigation页面复制了示例，但仍然显示相同的错误，有人知道这里的问题在哪里吗？我在互联网上搜索了一半，却找不到解决方法

我的package.json：

{
  "name": "BusinessCard",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "@react-native-community/masked-view": "^0.1.10",
    "@react-navigation/native": "^5.7.0",
    "@react-navigation/stack": "^5.7.0",
    "react": "^16.13.1",
    "react-native": "^0.63.0",
    "react-native-gesture-handler": "^1.6.1",
    "react-native-reanimated": "^1.9.0",
    "react-native-safe-area-context": "^3.1.1",
    "react-native-safe-area-view": "^1.1.1",
    "react-native-screens": "^2.9.0"
  },
  "devDependencies": {
    "@babel/core": "^7.10.4",
    "@babel/runtime": "^7.10.4",
    "babel-jest": "^24.9.0",
    "jest": "^24.9.0",
    "metro-react-native-babel-preset": "^0.53.1",
    "react-test-renderer": "16.8.3"
  },
  "jest": {
    "preset": "react-native"
  }
}

我复制的代码：

import 'react-native-gesture-handler';
import * as React from 'react';
import { StyleSheet, View, Text, TouchableHighlight } from "react-native";
import { NavigationContainer } from '@react-navigation/native';
import { createStackNavigator } from '@react-navigation/stack';

function HomeScreen() {
  return (
    <View style={{ flex: 1, alignItems: 'center', justifyContent: 'center' }}>
      <Text>Home Screen</Text>
    </View>
  );
}

const Stack = createStackNavigator();

function App() {
  return (
    <NavigationContainer>
      <Stack.Navigator>
        <Stack.Screen name="Home" component={HomeScreen} />
      </Stack.Navigator>
    </NavigationContainer>
  );
}

export default App;

错误：

Answer 1

在较新版本的React Navigation中，我们必须手动安装react-native-safe-area甚至react-native-screens。我已经通过sudo npm install react-native-safe-area，sudo npm install react-native-screens解决了类似的问题。然后从我的Android清除应用数据，然后重新安装该应用。打开新的终端（Ubuntu 20.04 LTS），然后运行npm start。试试这个，可能会有所帮助。

Answer 2

您要尝试：cd ios && pod安装&& cd .. 然后关闭应用程序，关闭所有终端并重建您的应用程序。希望能帮到您。

Answer 3

我只有android解决方案。那就是您只需要按照以下步骤在您的终端中即可。

[your project path]\> cd android并输入。

然后，如果您使用的是PowerShell，只需在下面键入命令。

[your project path]\android\> ./gradlew clean

如果您在cmd中，请输入以下命令。

[your project path]\android\> gradlew clean

然后重新启动您的本机项目。
