Flutter AMSupportURLConnectionDelegate 两者都实现了？？错误

Question

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

有没有办法解决这个问题。我不确定问题是否写在那里。

Answer 1

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

通过执行以下操作，我能够清除我的这个问题：

• 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。

Answer 2

我遇到了这个错误

类 AMSupportURLConnectionDelegate 在 /usr/lib/libauthinstall.dylib 中都实现了

解决方案： 请打开 podfile 并使用此脚本进行更新

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

运行您的应用程序。

尝试在构建阶段选项卡的运行脚本中选择仅用于安装构建。
