我正在使用 React Native 和 Expo 尝试构建底部选项卡导航,但不确定导致错误的原因,我使用 React Navigation6
应用程序.js:
import React from 'react';
import { StatusBar } from 'expo-status-bar';
import { StyleSheet, Text, View } from 'react-native';
import { createBottomTabNavigator } from "@react-navigation/bottom-tabs";
import { NavigationContainer } from '@react-navigation/native';
import BottomBar from './src/Navbar/BottomBar';
export default function App() {
return(
<NavigationContainer>
<BottomBar/>
</NavigationContainer>
)
};
错误:
Unable to resolve module src/Screens/Navigation/BottomNav from /Users/wafaturaifi/Desktop/Requests/App.js: src/Screens/Navigation/BottomNav could not be found within the project or in these directories:
node_modules
If you are sure the module exists, try these steps:
1. Clear watchman watches: watchman watch-del-all
2. Delete node_modules and run yarn install
3. Reset Metro's cache: yarn start --reset-cache
4. Remove the cache: rm -rf /tmp/metro-*
BottomBar.js:
import React, { useEffect, useContext } from "react";
import { View } from "react-native";
import { createBottomTabNavigator } from "@react-navigation/bottom-tabs";
import HomeScreen from '../Screens/Home';
import MoreScreen from '../Screens/More';
import PostScreen from '../Screens/Post';
import RequestsScreen from '../Screens/Requests';
import SummaryScreen from '../Screens/Summary';
const Tab = createBottomTabNavigator();
const BottomBar=() => {
return (
<Tab.Navigator>
<Tab.Screen name="Home" component={HomeScreen} />
<Tab.Screen name="Summary" component={SummaryScreen} />
<Tab.Screen name="Add" component={AddScreen} />
<Tab.Screen name="Requests" component={RequestsScreen} />
<Tab.Screen name="More" component={MoreScreen} />
</Tab.Navigator>
);
}
export default BottomBar;

最佳答案
此问题是因为要使用 React Navigation,您需要运行以下命令
npm install react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view
或
yarn add react-native-reanimated react-native-gesture-handler react-native-screens react-native-safe-area-context @react-native-community/masked-view
关于javascript - React Native 底部选项卡导航不起作用,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/71560069/
