React Native iOS：重复符号，即`重复符号_OBJC_METACLASS _ $ _ RCTWebSocketModule`

Question

因此，我有可怕的多少重复符号，原因不明。

例

duplicate symbol _OBJC_METACLASS_$_RCTWebSocketModule

duplicate symbol _OBJC_METACLASS_$_RCTWebSocketModule in:
    /Users/michaelstokes/Library/Developer/Xcode/DerivedData/Clustr-fkpfvfogtttxepgdsdrkmamfpvax/Build/Intermediates.noindex/ArchiveIntermediates/clustr/BuildProductsPath/Release-iphoneos/libReact.a(RCTWebSocketModule.o)
    /Users/michaelstokes/Library/Developer/Xcode/DerivedData/Clustr-fkpfvfogtttxepgdsdrkmamfpvax/Build/Intermediates.noindex/ArchiveIntermediates/clustr/BuildProductsPath/Release-iphoneos/libRCTWebSocket.a(RCTWebSocketModule.o)
ld: 284 duplicate symbols for architecture arm64

我有点困惑，为什么虽然这是我的图书馆名单

我的Podfile目前是这样的，因为我调查了重复符号背后的原因

当我收到此错误时，从Pods目标中删除React可以解决问题。

它是由CocoaPods添加React之间的冲突以及React在链接时通常如何添加到库部分引起的。
