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

Question

所以，由于未知原因我有多少重复的符号。

示例

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，为什么虽然这里是我的图书馆清单

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可解决此问题。

这是由于CocoaPods添加React和通常如何在链接时将React添加到库部分之间的冲突引起的。
