XCode 中的 Flutter 项目：“多个命令生成...FBSDKCoreKit.framework”

Question

我将 iOS 升级到 16.4.1（这需要我将 XCode 升级到 14.3，这需要我将 mac 操作系统从 12 升级到 13）后，在尝试构建 iOS Flutter 应用程序时收到此错误：

多个命令生成 \'/Users//Library/Developer/Xcode/DerivedData/Runner-bczatismiambuefczuntppsiskse/Build/Products/Debug-iphoneos/Runner.app/Frameworks/FBSDKCoreKit.framework\'

\n

目标\'Runner\'（项目\'Runner\'）具有来自\'/Users//Documents/AndroidStudioProjects//ios/Pods/FBSDKCoreKit/XCFrameworks/FBSDKCoreKit.xcframework/ios-arm64/FBSDKCoreKit.framework\'的复制命令到 \'/Users/<我的名称/Library/Developer/Xcode/DerivedData/Runner-bczatismiambuefczuntppsiskse/Build/Products/Debug-iphoneos/Runner.app/Frameworks/FBSDKCoreKit.framework\'

\n

该命令取决于目标\'Runner\'（项目\'Runner\'）中的命令：脚本阶段\xe2\x80\x9c[CP] Embed Pods Frameworks\xe2\x80\x9d

我还没有添加任何新的软件包、pod、插件……就在我的 iOS 和 Mac OS（和 XCode）更新之后，我收到了这个错误。

\n

我已经检查了这个 stackoverflow 问题，这对我没有帮助。

错误消息提到了\xe2\x80\x9c[CP] Embed Pods Frameworks\xe2\x80\x9d这里是Build PhasesXCode 中的屏幕截图：

\n

这是我的 XCode 中“构建阶段”>“复制捆绑资源”部分的屏幕截图（如果有的话）。（Info.plist里面没有）

编辑：我添加了额外的屏幕截图，显示项目中名为“Info.plist”的每个文件（通过 Mac OS Finder 搜索）。

\n

第一个屏幕截图显示了主 Info.plist 文件。\n

在第二个屏幕截图中，您可以在同一项目中看到 9 个 Info.plist 文件，但它们都在 Pod 内：

\n

\n
• FBSDK核心套件
\n
• Google-移动广告-SDK
\n
• FBSDK登录工具包
\n
• Google用户消息平台
\n
• FBAEM套件
\n
• Firebase分析
\n
• 谷歌应用测量
\n
• FBSDKCoreKit_基础知识
\n
• GoogleAppMeasurement（在另一个文件夹内，如上面 2 行）

首先，尝试清洁 Pod：

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile
flutter run
