React-native 链接在手动删除链接后不会重新链接

问：

该命令在我第一次安装依赖项时正常工作。react-native linknpm

在调试期间，我手动删除了 iOS 项目中 Libraries 和 Frameworks 文件夹的内容，从那时起，该命令无法再次链接它们。react-native link

“我的库”和“框架”文件夹为空：

我的也是空的，只有一些从 Pods 导入的。具体和阶段。Project Settings > Target > Build PhasesLink Binary With LibrariesEmbed Frameworks

但是，该命令返回成功：react-native link

$ react-native link

似乎是一个缓存问题，但不确定在哪里清理其缓存。
