反应本机iOS:重复符号，即“重复符号_OBJC_METACLASS_$_RCTWebSocketModule`”

Question

所以我害怕有多少符号因为未知的原因而重复。

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

我有点搞不懂为什么，这是我的图书馆名单

我的Podfile现在是这样的，因为我调查了重复符号背后的原因

当我得到这个错误时，从Pods目标中移除React修复了这个问题。

这是由CocoaPods添加React与React如何添加到库部分之间的冲突引起的，通常是在链接时。
