我最近在iOS平台上遇到问题。我可以创建一个示例计数器应用程序并运行它，但是当我尝试运行自己的项目时，该项目包含一些库，包括firebase，google_sign_in，google map等，pod install总是失败。
错误消息是：

尽管我没有在Mac中安装Android SDK，但我知道Android项目可以正常运行，并且已上传到Google Play。
我正在按照这些库中的说明进行操作，在info.plist中插入某些配置，然后将“ GoogleService-Info.plist”放置在适当的位置。
我对pod在Mac中的工作方式不是很熟悉，但是请告诉我您是否有任何线索，我将不胜感激！
谢谢
答案 0 :(得分：0)
事实证明，我需要将pod降级到1.7.5版，我想这个问题已经解决了。
