由于 Cocoapods 安装失败，iOS Framework 添加失败

Question

当我尝试为 IOS 构建我的 unity 项目时，Unity 产生了一个与 Firebase 和 Cocoapods 相关的错误。我找不到任何解决办法。你能建议我解决这个错误吗？谢谢

Unity 控制台错误消息；

由于 CocoaPods 安装失败，iOS 框架添加失败。这可能会导致无法运行的 Xcode 项目。

失败后执行“pod repo update”，成功。然后再次尝试“pod install”，但仍然失败。这可能是由于 CocoaPods 安装损坏所致。请参阅:https://guides.cocoapods.org/using/troubleshooting.html寻找潜在的解决方案。

pod 安装输出:

Analyzing dependencies [!] CocoaPods could not find compatibleversions for pod "GoogleAppMeasurement": In Podfile:Firebase/Analytics (= 6.32.2) was resolved to 6.32.2, which depends onFirebase/Core (= 6.32.2) was resolved to 6.32.2, which depends onFirebaseAnalytics (= 6.8.2) was resolved to 6.8.2, which depends onGoogleAppMeasurement (= 6.8.2)

Google-Mobile-Ads-SDK (~> 7.68) was resolved to 7.69.0, which dependson GoogleAppMeasurement (~> 7.0)

Answer 1

Podfile 中的 Firebase 和 Google-Mobile-Ads-SDK 版本规范不兼容。

Firebase 6.x 与最高版本为 7.67.0 的 Google-Mobile-Ads-SDK 兼容。 7.67.1 之后，需要 Firebase 7.x。
