是否遵循了本入门指南中的所有步骤？ reactnavigation.org/docs/getting-started 【参考方案1】：npm install @react-navigation/native
如果使用博览会：
expo install react-native-gesture-handler react-native-reanimated react-native-screens react-native-safe-area-context @react-native-community/masked-view
同时运行：
npm install react-navigation
【讨论】：
【参考方案2】：这个错误是因为你没有安装 react-navigation。
运行：
npm install react-navigation
npm start -- --reset-cache
【讨论】：
【参考方案3】：最好的解决方案是删除你的 node_modules 和 package-lock.json 并尝试 npm install，它对我有用
【讨论】：
【参考方案4】：我已经通过重新安装/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
解决问题
npm start -- --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
run npm start -- --reset-cache
run app
