如何使用我的react nav解决依赖性问题

Question

所以我是一个新手，正在努力学习开发应用程序。我试图学习如何使用React Navigation，所以我安装了它和dependencies，但当我尝试使用它时，我遇到了一些错误。运行npm启动后第一个出现在cmd中：

Some of your project's dependencies are not compatible with currently installed expo package version:
- react-native-screens - expected version range: 2.0.0-alpha.12 - actual version installed: ^2.0.0-alpha.12
Your project may not work correctly until you install the correct versions of the packages.
To install the correct versions of these packages, please run: expo install [package-name ...]

然后当我在安卓sim中启动应用程序时，我会得到这个：

Unable to resolve "@react-navigation/drawer" from "App.js"
Failed building JavaScript bundle.

这是我的代码：

import React from 'react';
import { StyleSheet, Text, View, Platform, Image, ImageBackground } from 'react-native';
import {Button} from 'native-base';
import { render } from 'react-dom';
import Search from './src/search';
import Landing from './src/landing';
import {NavigationContainer} from '@react-navigation/native'
import {createDrawerNavigator} from '@react-navigation/drawer'
import {createStackNavigator} from '@react-navigation/stack'
import {createMaterialBottomTabNavigator} from '@react-navigation/material-bottom-tabs'
import {createMaterialTopTabNavigator} from '@react-navigation/material-top-tabs'

var myBackground = require('./assets/icons/landing.jpg');
const Drawer = createDrawerNavigator();
const Stack = createStackNavigator();
const MaterialBottomTabs = createMaterialBottomTabNavigator();
const MaterialTopTabs = createMaterialTopTabNavigator();

export default class App extends React.Component {
state = {
}
createHomeStack = () =>
<Stack.Navigator>
<Stack.Screen  name="Feed"/>
</Stack.Navigator>
createTopTabs = () =>
{
return <MaterialTopTabs.Navigator>
<MaterialTopTabs.Screen name="Tab1" Component={Landing}/>
</MaterialTopTabs.Navigator>
}
render() {
return (
<View style={styles.container}>
<NavigationContainer>
<Drawer.Navigator>
<Drawer.Screen name="Home" Component="Landing"/>
<Drawer.Screen name="Search" Component="Search"/>
<Drawer.Screen name="Home"/>
</Drawer.Navigator>
</NavigationContainer>
</View>
);
}
}
const styles = StyleSheet.create({
container: {
flex: 1,
marginTop: Platform.OS === "android" ? 50 : 0
},
});

有人知道我为什么会犯这些错误吗？在开始之前，我安装了React Nav。提前感谢！

因此，正如您的pacakge.json所示，您还没有安装用于抽屉和堆叠的包。解决抽屉问题后，您将遇到堆叠问题。。按照以下步骤复制您的问题

有关React Navigation Version 5.x 的更多信息

使用以下方法安装抽屉包：

npm i -s @react-navigation/drawer

使用以下方法安装导航堆栈：

npm i -s @react-navigation/stack

使用以下方法安装材料底部标签：

npm i -s @react-navigation/material-bottom-tabs

使用以下方法安装材料顶部选项卡：

npm i -s @react-navigation/material-top-tabs

• 您应该按照以上所有步骤解决项目中的问题

安装完以上所有依赖项后，您需要清理并重建项目，并从模拟器中卸载以前的版本，然后再次运行
