Ios 颤振项目吊舱安装失败，错误为419

我最近在iOS平台上遇到了一个问题。我可以创建一个示例计数器应用程序并运行它，但当我尝试运行我自己的项目时，它有一些库，包括firebase、google\u sign\u、google map等，

pod安装

总是失败

错误消息是：

虽然我没有在我的mac电脑上安装Android SDK，但我知道Android项目运行良好，并已上传到google play

我按照这些库中的说明，在info.plist中插入某些配置，并将“GoogleService info.plist”放在适当的位置

我对mac中的pod的工作原理不是很熟悉，但是如果你有任何线索，请告诉我，我会非常感激的

谢谢

事实证明我需要将pod降级到1.7.5版，我想问题已经解决了
