React native “无法解决”@react导航/本机“；从「；App.js"；-反应本机+；如何解决？

未定义无法从

App.js

解析模块

@react-navigation/native

：@react-navigation/native在项目中找不到

如果确定模块存在，请尝试以下步骤：

 1. Clear watchman watches: watchman watch-del-all
 2. Delete node_modules: rm -rf node_modules and run yarn install
 3. Reset Metro's cache: yarn start --reset-cache
 4. Remove the cache: rm -rf /tmp/metro-*

发生此错误是因为您尚未安装react导航

运行：

如果使用expo：

expo install react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view

还运行：

npm install react-navigation

---

我通过重新安装/更新这些软件包解决了这个问题

npm install --save react-native-gesture-handler react-native-reanimated react-native-screens

为…耍把戏

npm启动--reset cache

但执行以下操作确实成功：

删除

node_modules&package-lock.json从手机中删除应用程序

---

最好的解决方案是删除您的node_模块和package-lock.json，然后尝试npm安装，这对我很有用

尝试将这一行添加到您的metro.config.js

sourceExts: ['jsx', 'js', 'ts', 'tsx', 'json'],

---

是否遵循本入门指南中给出的所有步骤？

npm install --save react-native-gesture-handler react-native-reanimated react-native-screens

run npm start -- --reset-cache
run app
