我没有经验，所以我不能确定问题出在哪里.谢谢你的帮助.

我克隆了这个回购协议:https://github.com/flatlogic/react-native-starter.git

并试图遵循以下步骤:

Clone the repo

git克隆https://github.com/flatlogic/react-native-starter.git

Navigate to clonned folder and Install dependencies

cd react-native 启动器&amp&amp；Yarn 安装

Install Pods

cd ios&amp&amp；pod 安装

当我安装pod时，我发现了这个错误.
