我尝试清理构建文件夹，再次运行 pod install 但没有任何效果。我陷入了这个错误。我无法找到导致此错误的原因。另外，我检查了 myApp > Libraries 文件夹，没有任何内容（空文件夹）。

将react-native-unimodules库添加到我正在开发的应用程序后，我遇到了完全相同的错误。

经过几个小时尝试不同的解决方案后，我们通过将react-native-unimodules库从当前的0.14.7版本降级到0.13.3来修复错误。

• 更改了package.json中的react-native-unimodules版本
• 重新安装了软件包（为我安装了yarn）
• cd ios，然后 pod deintegrate （只是为了确定），然后 pod install
• 在 XCode 中转到“产品”选项卡并从那里清理构建文件夹
• 启动应用程序并成功编译

希望它可以帮助遇到该问题的其他人。

SOLVED @Jan 20 2022

React-native-unimodules是罪魁祸首。由于 expo 已自行更新，react-native-unimodules 现已弃用。

yarn remove react-native-unimodules

或者

npm uninstall react-native-unimodules

在 Pod 文件中

# require_relative '../node_modules/react-native-unimodules/cocoapods.rb'
# use_unimodules!

还要清理您的 AppDelegate.m 和 AppDelegate.h

删除节点模块

    pod install

进行构建并开始使用。世博包将不起作用。现在从 package.json 中删除当前正在使用的 expo 软件包，然后再次使用yarn install，然后在 iOS 目录中进行 pod install 并进行构建。仍然 expo 包无法工作，现在搜索您想要使用的任何 expo 包，然后按照文档进行操作。稍后谢谢我。

尝试升级expo-permissions到最新版本
