react-native - 无法解析模块@react-native-async-storage/async-storage

Question

将 aws-amplify 添加到项目后出现此错误，是否根据文档完成了 aws-amplify 的设置，然后是 pod install 和 react-native run-ios我也尝试过按照下面的错误建议更改导入语句，但仍然不起作用，在此先感谢。

  node_modules/@aws-amplify/core/node_modules
  node_modules
  ../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-*

安装 Amplify 库:here ,

yarn add @react-native-async-storage/async-storage

之后，如果出现问题，请尝试清理项目，

rm -rf $TMPDIR/metro-* && rm -rf $TMPDIR/haste-* && watchman watch-del-all && yarn cache clean --force && rm -rf ios/build && rm -rf node_modules/

yarn install

rm -rf pods && pod install
