iOS 由于 Cocoapods 安装失败，框架添加失败

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。我找不到任何解决方案。你能建议我解决这个错误吗？ 谢谢

Unity 控制台错误消息；

iOS 由于 CocoaPods 安装失败，框架添加失败。这可能会导致无法正常运行 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 了解可能的解决方案。

pod 安装输出：

Analyzing dependencies [!] CocoaPods could not find compatible versions for pod "GoogleAppMeasurement": In Podfile: Firebase/Analytics (= 6.32.2) was resolved to 6.32.2, which depends on Firebase/Core (= 6.32.2) was resolved to 6.32.2, which depends on FirebaseAnalytics (= 6.8.2) was resolved to 6.8.2, which depends on GoogleAppMeasurement (= 6.8.2)

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

Answer 1

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

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

Answer 2

在更改 Firebase 版本之前可以检查用于 Firebase 的所有包是否具有相同的版本。

例如：Analytics 8.1.0 和 Messaging 8.9.0 -> Analytics 8.9.0 和 Messaging 8.9.0

对我来说它成功了。
