Question

我的Podfile看起来像这样

platform :ios, '11.2'

target 'live-quiz' do
    use_frameworks!
    pod 'Fabric'
    pod 'Crashlytics'
    pod 'Kingfisher'
    pod 'Alamofire'
    pod 'youtube-ios-player-helper'
    pod 'Firebase/Core'
    pod 'Firebase/Auth'
    pod 'Firebase/Firestore'
    pod 'Firebase/Database'
    pod 'Firebase/Messaging'
    pod 'Firebase/Storage'
    pod 'CodableFirebase'
    pod 'FBSDKLoginKit'
    pod 'CountryPickerSwift'
    pod 'lottie-ios'
    pod 'SwiftySound'
end

我之前可以运行pod更新，但是今天运行pod update之后

Analyzing dependencies
[!] CocoaPods could not find compatible versions for pod "Firebase/Core":
  In Podfile:
    Firebase/Core

Specs satisfying the `Firebase/Core` dependency were found, but they required a higher minimum deployment target.
CocoaPods could not find compatible versions for pod "GoogleUtilities/AppDelegateSwizzler":
  In Podfile:
    Firebase/Core was resolved to 5.8.0, which depends on
      FirebaseAnalytics (= 5.1.2) was resolved to 5.1.2, which depends on
        GoogleUtilities/AppDelegateSwizzler (~> 5.2.0)

Specs satisfying the `GoogleUtilities/AppDelegateSwizzler (~> 5.2.0)` dependency were found, but they required a higher minimum deployment target.
CocoaPods could not find compatible versions for pod "gRPC-Core":

    Firebase/Firestore was resolved to 5.8.0, which depends on
      FirebaseFirestore (= 0.13.3) was resolved to 0.13.3, which depends on
        gRPC-ProtoRPC (~> 1.0) was resolved to 1.14.1, which depends on

                gRPC-Core (= 1.14.1)

看起来gRPC-C ++ / Implementation和gRPC / Main中的gRPC-Core使用不同的版本（1.14.0、1.14.1）如何解决此问题？

Answer 1

请重新运行

pod update

他们修复了它。请检查： https://github.com/firebase/firebase-ios-sdk/issues/1845

已解决的Firebase / Core依赖关系导致的CocoaPods错误。（＃1845，＃8110）

Answer 2

我有同样的问题，以下对我有用。更改您的Podfile：

来自：

platform :ios, '11.2'

收件人：

platform :ios, '9.0'

Answer 3

现在：Google在5.8.1版中解决了此问题-2018年9月19日

从Firebase支持

是的，即使将平台降级，问题仍然存在版本，我已经与我们的工程师进行了协调，并等待着他们的回应。现在，我可以通过降级来正确安装我的Firebase / Core版本为5.7.0，即“ Firebase / Core”，“ 5.7.0”。然后做一个pod安装/ pod更新。

Answer 4

我遇到了同样的问题，请尝试添加：

pod 'BoringSSL-GRPC', '0.0.3'

在项目的 Podfile 中然后运行：

pod install

gRPC-Core 1.14.0和1.14.1的pod更新问题
