CocoaPods 找不到 pod“FirebaseCore”的兼容版本：在快照中 (Podfile.lock)

Question

我正在尝试添加我在 GitHub 上找到的Geofirestore pod ，以便我可以将地理位置经度和纬度添加到社交媒体应用程序中的帖子中。我的 pod 文件看起来像这样

pod 'Firebase/Core'
pod 'Firebase/Auth'
pod 'Firebase/Firestore'
pod 'Firebase/Storage', '~> 4.0'
pod 'Geofirestore'

我在我的终端中运行了 pod repo update 和 pod install 但它不起作用，我收到了这个错误。

[!] CocoaPods could not find compatible versions for pod "FirebaseCore":
  In snapshot (Podfile.lock):
    FirebaseCore (= 4.0.20, ~> 4.0)

  In Podfile:
    Firebase/Core was resolved to 4.13.0, which depends on
      FirebaseAnalytics (= 4.2.0) was resolved to 4.2.0, which depends on
        FirebaseCore (~> 4.0)

    Firebase/Core was resolved to 4.13.0, which depends on
      FirebaseCore (= 4.0.20)

    Geofirestore was resolved to 0.1.0, which depends on
      FirebaseCore (~> 5.0.3)

[!] Automatically assigning platform `ios` with version `11.4` on target `My App` because no platform was specified. Please specify a platform for this target in your Podfile. See `https://guides.cocoapods.org/syntax/podfile.html#platform

Answer 1

您'Geofirestore'的 Podfile 中有：如错误消息所示，它需要FirebaseCore (~> 5.0.3).

你'Firebase/Storage', '~> 4.0'的 Podfile 中有，它让你坚持使用FirebaseCore (~> 4.0).

要同时使用两者，您需要从 Firebase 4 升级到 Firebase 5。即您需要：

pod 'Firebase/Storage', '~> 5.0'
