问题描述
Xcode 12.3
可可豆 1.10.1
反应原生 CLI 4.13.1
我在 Xcode“存档”构建任务中的链接阶段 (library not found for -lRCTTypeSafety) 构建 React Native 应用程序时反复失败。 （“产品”>“存档”）当我在“清理构建文件夹”之后运行第一个“构建”时，它失败并出现相同的错误。
当我运行通常会成功的“构建”任务时不会发生这种情况，但“清理后的第一次构建”行为与“存档”任务的行为方式一致，这似乎运行了隐式“清理”首先，它们似乎是一个类似的失败案例。
我在网上找到的所有建议的补救措施都没有奏效。我使用的是工作区，而不是项目文件。 FWIW，我已经确认使用 xcodebuild 也会发生同样的情况。 （与 Xcode gui 不同。）xcodebuild clean build 和 xcodebuild archive 都可靠地失败，但如果 xcodebuild build 不是 clean 之后的第一个构建，则它会成功。
链接器命令失败时缺少几个 Pod 库。在成功运行时，xcodebuild build 操作在 -L 链接命令中具有以下额外的 clang 标志，这些标志在失败的尝试中丢失：

成功的 build 操作没有 WriteAuxiliaryFile、CompileC 或 Libtool 日志行，因此看起来 clean 之后失败的第一次尝试是实际上正确构建 Pod 文件，只是没有提供链接器命令的必要路径。
失败构建中缺失库的 Libtool 行如下所示：
Libtool /Users/<user>/Library/Developer/Xcode/DerivedData/<project>-bcgmbzkfkmobskcxnhtpmhoehiux/Build/Products/Release-iphoneos/RCTTypeSafety/libRCTTypeSafety.a normal (in target 'RCTTypeSafety' from project 'Pods')
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static -arch_only arm64 -D -syslibroot /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS14.3.sdk -L/Users/<user>/Library/Developer/Xcode/DerivedData/<project>-bcgmbzkfkmobskcxnhtpmhoehiux/Build/Products/Release-iphoneos/RCTTypeSafety -filelist /Users/<user>/Library/Developer/Xcode/DerivedData/<project>-bcgmbzkfkmobskcxnhtpmhoehiux/Build/Intermediates.noindex/Pods.build/Release-iphoneos/RCTTypeSafety.build/Objects-normal/arm64/RCTTypeSafety.LinkFileList -dependency_info /Users/<user>/Library/Developer/Xcode/DerivedData/<project>-bcgmbzkfkmobskcxnhtpmhoehiux/Build/Intermediates.noindex/Pods.build/Release-iphoneos/RCTTypeSafety.build/Objects-normal/arm64/RCTTypeSafety_libtool_dependency_info.dat -o /Users/<user>/Library/Developer/Xcode/DerivedData/<project>-bcgmbzkfkmobskcxnhtpmhoehiux/Build/Products/Release-iphoneos/RCTTypeSafety/libRCTTypeSafety.a
并且我已检查输出文件 libRCTTypeSafety.a 是否存在于为上述 -o 标志指定的路径中。包含该文件的目录包含在所提供的缺失 -L 标志中，因此确实看起来好像在编译和链接之间只是遗漏了一些步骤。
任何帮助将不胜感激！
