ios - 在Xcode中添加Firebase时如何解决 "duplicate symbol"

Question

我无法解决错误“重复符号”。

错误是

duplicate symbol _GSDK_NSClassFromString in: .../Pods/FirebaseCore/Frameworks/FirebaseCore.framework/FirebaseCore(overload_9ea29fd47bf44ee000bc4282b65dac06.o)
 /Pods/GoogleSymbolUtilities/Frameworks/frameworks/GoogleSymbolUtilities.framework/GoogleSymbolUtilities(overload.o)

duplicate symbol _GSDK_objc_getClass in: .../Pods/FirebaseCore/Frameworks/FirebaseCore.framework/FirebaseCore(overload_9ea29fd47bf44ee000bc4282b65dac06.o)
/Pods/GoogleSymbolUtilities/Frameworks/frameworks/GoogleSymbolUtilities.framework/GoogleSymbolUtilities(overload.o)

duplicate symbol _GSDK_objc_getProtocol in:    ...Pods/FirebaseCore/Frameworks/FirebaseCore.framework/FirebaseCore(overload_9ea29fd47bf44ee000bc4282b65dac06.o)
    .../Pods/GoogleSymbolUtilities/Frameworks/frameworks/GoogleSymbolUtilities.framework/GoogleSymbolUtilities(overload.o)

duplicate symbol _GSDK_objc_lookUpClass in:        ...Pods/FirebaseCore/Frameworks/FirebaseCore.framework/FirebaseCore(overload_9ea29fd47bf44ee000bc4282b65dac06.o)
    ...Pods/GoogleSymbolUtilities/Frameworks/frameworks/GoogleSymbolUtilities.framework/GoogleSymbolUtilities(overload.o)

ld: 4 duplicate symbols for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我更新并安装了 Podfile。但它没有用。

Pod 文件

target 'game' do

  # Pods for game
  pod 'Firebase'
  pod 'Firebase/AdMob'
end

我之前可以添加 Firebase。但是当我不小心删除了“FirebaseCore.framework”时。 之后我删除了 Pod 并重新安装了 Firebase，但它没有用。

我该如何解决？

我遇到了同样的问题。似乎其他链接器标志中的 -all_load 标志导致了这一点。
