Flutter AMSupportURLConnectionDelegate 在两者中都实现了？错误

Question

自从我将项目迁移到 Apple Silicon mac 后，我遇到了许多问题。我终于设法减少了问题，但不确定答案。

有什么办法可以解决这个问题吗？我不确定问题是否写在那里。

Answer 1

我收到这个错误

AMSupportURLConnectionDelegate 类在 /usr/lib/libauthinstall.dylib 中实现

笔记：

如果您已从 <=2.8 更新到 flutter 2.10，请先尝试此操作

flutter pub upgrade 

解决方案： 请打开podfile并使用此脚本更新

installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end

flutter clean
flutter pub get
cd ios
pod install  

或者您可以尝试下面的 M1 来代替最后一个命令

arch -x86_64 pod install // for M1 

运行您的应用程序。

Answer 2

最近，在更新到 Flutter 2.x 后，我的 M1 macbook 也收到了相同的“Xcode 构建错误输出”。

我能够通过执行以下操作来解决我的这个问题：

• 将目录更改为项目的路径和子目录：

your_project/build/ios/Debug-iphonesimulator/

• 运行 $ xattr -lr Runner.app
• 运行 $ xattr -cr Runner.app

显然，flutter 项目在包含 Finder 信息的项目应用程序包中具有扩展属性，这会导致错误。
