推荐答案

当您部署应用程序(或在模拟器中使用)时，数据库会被复制到平台，并且与 www/文件夹不同.如果您想从应用中删除数据

When you deploy an app (or use in emulator), the database is copied to the platform and isn't the same as www/ folder. If you want to remove data from app

要么卸载再安装(它会再次从www复制)

Either uninstall and install (it will copy again from www)

或

清除应用程序数据(这将清除所有存储并使应用程序与最初安装的一样)

Clear Application Data (that will clean all storage and make app as originally installed)

如果你渴望找到路径(虽然我想不出用例)，你可以运行 make use of package like https://www.npmjs.com/package/react-native-fs 并在 App.js 中运行代码以查找当前目录和 console.log.

If you're keen to find path (though I couldn't think of a usecase), You can run make use of package like https://www.npmjs.com/package/react-native-fs and run code within App.js to find current directory and console.log it.
