我目前正在尝试使用 Ionic React（电容器）实现 RevenueCat SDK，在使用 Ionic Appflow 构建应用程序时出现以下错误

@enc_life 的评论对我有用（在 Flutter 应用程序上，而不是 React，但我猜 iOS 部分的工作原理是一样的）：
pod install --repo-update
此后，一切都如魔法般顺利。
我收到的错误消息是
[!] CocoaPods could not find compatible versions for pod "PurchasesHybridCommon":
In Podfile:
purchases_flutter (from `.symlinks/plugins/purchases_flutter/ios`) was
resolved to 1.4.3, which depends on PurchasesHybridCommon (= 1.4.5)
None of your spec sources contain a spec satisfying the dependency:
`PurchasesHybridCommon (= 1.4.5)`.
尝试清理你的podfile并重新安装； 移至 ios/App 文件夹：
pod cache clean --all
rm -rf Podfile.lock
pod install
