完整的日志
[!] CocoaPods could not find compatible versions for pod "firebase_analytics":
In Podfile:
firebase_analytics (from `.symlinks/plugins/firebase_analytics/ios`)
Specs satisfying the `firebase_analytics (from `.symlinks/plugins/firebase_analytics/ios`)` dependency were found, but they required a higher minimum deployment target.
有没有人知道为什么它来了，因为它以前工作得很好。
尝试添加依赖项:
firebase_core: ^1.0.0
然后打开xcode，运行ios文件夹这将解决你的问题，
