我无法解决错误“重复的符号”.

错误是

@H_404_4@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.但它没有奏效.

Pod文件

@H_404_4@target 'game' do # Pods for game pod 'Firebase' pod 'Firebase/AdMob' end

以前可以添加Firebase.但是当我不小心删除“FirebaseCore.framework”.
之后,我删除了Pods并重新安装了Firebase,但它没有起作用.

我该如何解决？
