undefined无法从App.js解析模块@react-navigation/native：在项目中找不到@react-navigation/native。
如果您确定模块存在，请尝试下列步骤：

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-*
