CocoaPods 找不到 pod“FirebaseCore”的兼容版本

Question

当我尝试使用 Unity 云构建进行构建时，我收到了以下消息：

然后

>64226:              GoogleAppMeasurement (~> 5.7)

然后

/BUILD_PATH/jeko.lazaramobile1.appstore-ios/temp20200309-7398-19hbpik/Libraries/Plugins/iOS/GADUNativeCustomTemplateAd.h:5:9: 'GoogleMobileAds/GoogleMobileAds.h' file not found`

我的本​​地构建也因缺少“GoogleMobileAds/GoogleMobileAds.h”而失败

在我的 Mac 上，当我检查我的 pod 文件时，它看起来像：

    target 'UnityFramework' do
  pod 'FBSDKCoreKit', '~> 5.5'
  pod 'FBSDKLoginKit', '~> 5.5'
  pod 'FBSDKShareKit', '~> 5.5'
  pod 'Firebase/Analytics', '6.9.0'
  pod 'Firebase/Auth', '6.9.0'
  pod 'Firebase/Core', '6.9.0'
  pod 'Google-Mobile-Ads-SDK', '~> 7.42.1'
end

我不知道这里必须做什么。任何帮助将不胜感激。我发现我的 firebese.core 以某种方式被卡在 6.2 或 6.3 上，但需要 6.9。我读到我必须包含一些框架搜索路径，但这是一种手动方法，而不是可可豆方式，我不知道在哪里手动输入路径。

Answer 1

1. 删除 Pods/ 文件夹
2. 删除 Podfile.lock
3. pod 安装

享受吧！

Answer 2

从 Podfile 中删除版本说明符或至少减少限制。

Google-Mobile-Ads-SDK 和 Firebase/Analytics 都依赖于GoogleAppMeasurement，并且指定的版本不兼容。
