问题描述
我刚刚将Flutter版本升级到1.22.0。升级并为Firebase进行了一些更改后，我的Android应用开始工作，但无法在模拟器或物理设备上构建和运行iOS应用。
当我尝试在模拟器或物理设备中运行应用程序时，终端显示以下错误。模拟器运行在iOS 14上，而物理设备运行在14.0.1上。
Emulator: ld: symbol(s) not found for architecture x86_64
Actual device: ld: symbol(s) not found for architecture arm64
我还执行了以下命令，但仍然无法正常工作...
Flutter clean && \
rm ios/Podfile ios/Podfile.lock pubspec.lock && \
rm -rf ios/Pods ios/Runner.xcworkspace && \
Flutter run

该问题似乎是由于RevenueCat API引起的。当我在 pubspec.yaml 文件中注释了导入 purchases_Flutter 时，我能够安装该应用程序，但是在启动时崩溃，提示失去连接。
解决方法
关于stackoverflow，这里有两个不同的答案。如果我没记错的话，最后一次切换到“稳定”频道可以为我解决问题。
,升级到1.22.0后，我也遇到了问题，我还必须升级flutterFire软件包，这似乎是我的问题。
我在pubspec.yaml上使用的版本：
firebase_core: ^0.5.0
cloud_firestore: ^0.14.1+2
firebase_auth: ^0.18.1+1
firebase_analytics: ^5.0.0
cloud_functions: ^0.6.0+1
firebase_storage: ^4.0.1
firebase_crashlytics: ^0.1.0+3
firebase_messaging: ^7.0.2
在尝试运行时，它说通过运行pod repo update来更新CocoaPods规格，虽然这样做，但是仍然遇到相同的错误，然后运行pod install或pod update却得到了错误
尝试了以下命令：pod install --repo-update和pod update Firebase/Storage，但仍然收到相同的错误消息
rm -f ios / Runner.xcworkspace / xcshareddata / WorkspaceSettings.xcsettings为我解决了此问题
,只需删除旧的flutter安装文件夹，例如[.cache] / [pub-cache]，因为您可能已经升级了flutter版本，但是iOStools和其他工具指向的是旧版本，这会导致这些体系结构问题。
,最后，在进行了很多更改之后，我发现罪魁祸首是 purchases_flutter：^ 1.3.1 ”软件包。
当我从yaml文件中删除该软件包时，它便开始工作。 https://github.com/RevenueCat/purchases-flutter/issues/120已经打开了一个错误。
感谢大家的时间和帮助。
