XCode 中的 Flutter 项目：“多个命令产生...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，在尝试构建我的 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'

目标“Runner”（项目“Runner”）已将命令从“/Users//Documents/AndroidStudioProjects//ios/Pods/FBSDKCoreKit/XCFrameworks/FBSDKCoreKit.xcframework/ios-arm64/FBSDKCoreKit.framework”复制到“/Users/”

该命令取决于目标“Runner”（项目“Runner”）中的命令：脚本阶段“[CP] Embed Pods Frameworks”

---

我还没有添加任何新的包、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。

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

“[CP] Embed Pods Frameworks”

，所以这是 XCode 中

Build Phases

下的屏幕截图：

如果重要的话，这是我的 XCode 中“构建阶段”>“复制捆绑资源”部分的屏幕截图。 （那里没有

Info.plist

）

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）。

第一个屏幕截图显示了主要的 Info.plist 文件。

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：

• FBSDKCoreKit
• Google-移动广告-SDK
• FBSDK登录套件
• Google 用户消息平台
• FBAEM套件
• Firebase 分析
• GoogleAppMeasurement
• FBSDKCoreKit_基础知识
• GoogleAppMeasurement（在另一个文件夹内，如上面 2 行）

我的

flutter doctor

输出：

Answer 1

首先，尝试清洁烟弹：

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

Answer 2

在 xcode 中打开您的项目，然后转到项目目标中的常规，向下滚动到框架、库和嵌入内容，然后将 FBSDKCoreKit.xcframework 从“嵌入并签名”更改为“不嵌入”，这应该可以解决问题。
