这是我的错误信息:

error: Multiple commands produce '/Users/runner/Library/Developer/Xcode/DerivedData/slapshot-ios-bpixgzdbgfcmofhguehgrznwbjxl/Build/Intermediates.noindex/ArchiveIntermediates/slapshot-ios-example/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/Introspect.framework'

我必须添加:linkage =>:static到我的所有目标，而不仅仅是其中的一些，在运行pod deintegrate/pod install之前(归功于这个答案)。

在我的例子中，构建存档错误vs Xcode10

-1: Multiple commands produce '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a': 1) Target 'yoga' has a command with output '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a' 2) Target 'yoga' has a command with output '/Users/kk/Library/Developer/Xcode/DerivedData/react_carday_app-hjahojxsbvmmiyaklrhhuqljdfwv/Build/Intermediates.noindex/ArchiveIntermediates/react_carday_app/IntermediateBuildFilesPath/UninstalledProducts/iphoneos/libyoga.a'

在你的Podfile中应该有类似bellow的东西

post_install do |installer|
  installer.pods_project.targets.each do |target|
    if target.name == "React"
      target.remove_from_project
    end

    if target.name == "yoga"
      target.remove_from_project
    end
  end
end

然后运行pod install

这基本上意味着你有多个名为Info.plist的文件; 通常情况下没问题，但你的文件被设置为相同的目标会员。因此，修复方法是:单击每个文件并在右侧检查它们的目标成员，确保它们不重叠。

如果您手动创建实体的CoreDataClass和CoreDataProperties，请确保转到您的xcdatamodel并将检查器选项卡中的Codegen设置为“Manual/None”。如果设置为“类定义”，Xcode会自动为你创建一个重复的类。

在我的情况下，我有关于信息的错误。Plist复制输出文件:

warning: duplicate output file

** BUILD FAILED **

我解决了这个问题，从项目->目标->建筑阶段->复制捆绑资源

2022的答案

如果您有多个目标，请确保部署目标相同。
