Ios CocoaPods在安装GoogleMLKit人脸检测时找不到pod GoogleDataTransport的兼容版本

所以我尝试通过以下方式安装ML Kit人脸检测库，所以首先我在我的

podfile

中添加了这一行：

pod 'GoogleMLKit/FaceDetection'

不幸的是，在我尝试安装它之后，在终端上出现了以下错误：

[!] CocoaPods could not find compatible versions for pod "GoogleDataTransportCCTSupport":   In snapshot (Podfile.lock):
    GoogleDataTransportCCTSupport (= 2.0.1, ~> 2.0)

  In Podfile:

我添加了更多类似这样的吊舱：

pod 'MLKitCommon'
pod 'GoogleMLKit/MLKitCore'

但现在我在终端上发现了这个错误：

经过一段时间的研究，我试图运行

pod安装--repo-update

，但它仍然给我这个错误。还有什么办法解决这个问题吗？

这为我解决了这个问题：

pod去集成

sudo gem安装cocoapods clean

pod clean

pod设置

pod安装

我删除了

并运行了

。工作。

以上两种方法对我不起作用。我在使用Firebase“cloud\u firestore:2.2.0”和“google\u ml\u kit:^0.6.0”。事实证明，CloudFireStore（2.2.0）需要FirebaseSDK版本8.0.0。我不得不降级到2.0.0，并在ios/podfile的podfile开头粘贴“$FirebaseSDKVersion='7.11.0'”。这就是问题所在。

还有人有这样的问题吗？在我的例子中，这两种解决方案都不起作用，它说“没有一个规范源包含满足依赖关系的规范”，还有人存在这样的问题吗？在我的例子中，两种解决方案都不起作用，它说“没有一个规范源包含满足依赖关系的规范”
