我在我的Flutter应用程序中添加了firebase_analytics，并且在Android上运行良好。但是，在使用Codemagic构建应用程序时，当我尝试构建iOS版本时出现了一个含糊的错误。本地构建似乎没有问题。

Resolving dependencies of `Podfile`
[!] CocoaPods could not find compatible versions for pod "Firebase/Core":
In snapshot (Podfile.lock):
Firebase/Core (= 6.5.0)
In Podfile:
firebase_analytics (from `.symlinks/plugins/firebase_analytics/ios`) was resolved to 0.0.1, which depends on
Firebase/Core
It seems like you've changed the constraints of dependency `Firebase/Core` inside your development pod `firebase_analytics`.
You should run `pod update Firebase/Core` to apply changes you've made.

我的pubspec.lock文件正确引用了最新版本的firebase_analytics和firebase core：
firebase_analytics:
dependency: "direct main"
description:
name: firebase_analytics
url: "https://pub.dartlang.org"
source: hosted
version: "4.0.2"
firebase_core:
dependency: "direct main"
description:
name: firebase_core
url: "https://pub.dartlang.org"
source: hosted
version: "0.4.0+8"
我的Podfile.lock看起来不太奇怪（虽然我不知道应该寻找什么）:

pod update吗？ - Paul Beusterienpod update，但是我的 Podfile.lock 没有发生任何变化。 - bamnet# Uncomment the next line to define a global platform for your project。下一行看起来是这样的：# platform :ios, 'X.0'。其中的X.0代表了你的 iOS 平台版本。尝试将它的注释去掉，只需删除#符号即可。同时，查看报错提供的链接。 - MαπμQμαπkγVπ.0
