ios - 架构 x86_64 : referenced from: _YGConfigNew in libyoga. a(Yoga.o) 的 undefined symbol 问题

Question

我使用 xcode 10 并在尝试构建时收到以下错误:

Undefined symbols for architecture x86_64: "YGConfig::YGConfig(int ()(YGConfig, YGNode*, YGLogLevel, char const*, __va_list_tag*))", referenced from: _YGConfigNew in libyoga.a(Yoga.o) 

我的 podfile 看起来像:

target 'CrisisApp' do
# Uncomment the next line if you're using Swift or would like to use 
dynamic frameworks
# use_frameworks!

# Pods for CrisisApp

pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'CxxBridge'
]

pod 'Interactable', :path => '../node_modules/react-native-interactable'

pod 'Folly', :podspec => '../node_modules/react-native/third-party- 
podspecs/Folly.podspec'
pod 'yoga', :path => '../node_modules/react-native/ReactCommon/yoga'

pod 'ReactNativePermissions', :path => '../node_modules/react-native-permissions'

pod 'react-native-image-picker', :path => '../node_modules/react-native-image-picker'

pod 'rn-fetch-blob', :path => '../node_modules/rn-fetch-blob'

pod 'react-native-pdf', :path => '../node_modules/react-native-pdf'

pod 'lottie-ios', :path => '../node_modules/lottie-ios'

pod 'lottie-react-native', :path => '../node_modules/lottie-react-native'

pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'


target 'CrisisApp-tvOSTests' do
inherit! :search_paths
# Pods for testing
pod 'ReactNativePermissions', :path => '../node_modules/react-native-permissions'

pod 'react-native-image-picker', :path => '../node_modules/react-native-image-picker'

pod 'rn-fetch-blob', :path => '../node_modules/rn-fetch-blob'

pod 'react-native-pdf', :path => '../node_modules/react-native-pdf'

pod 'lottie-ios', :path => '../node_modules/lottie-ios'

pod 'lottie-react-native', :path => '../node_modules/lottie-react-native'

pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'

end

target 'CrisisAppTests' do
inherit! :search_paths
# Pods for testing
end

end

target 'CrisisApp-tvOS' do
# Uncomment the next line if you're using Swift or would like to use dynamic frameworks
# use_frameworks!

# Pods for CrisisApp-tvOS

end

我在 SO 上看到了另外两个类似的问题，但到目前为止没有回复，所以请帮忙

Answer 1

我认为有两种解决方案:

1) 您可以删除所有这些 pod 并在项目目标中添加依赖项链接框架和库，如下所示:

将它们添加到那里后，您可以从 pod 文件中删除这些行:

pod 'ReactNativePermissions', :path => '../node_modules/react-native-permissions'

pod 'react-native-image-picker', :path => '../node_modules/react-native-image-picker'

pod 'rn-fetch-blob', :path => '../node_modules/rn-fetch-blob'

pod 'react-native-pdf', :path => '../node_modules/react-native-pdf'

pod 'lottie-ios', :path => '../node_modules/lottie-ios'

pod 'lottie-react-native', :path => '../node_modules/lottie-react-native'

pod 'RNDeviceInfo', :path => '../node_modules/react-native-device-info'

如果您遇到更多与其他 RN 或 React 库相关的崩溃，请确保它们在链接的框架和库中。

2) 如果您的 RN 版本>0.60，您可以尝试使用自动链接，从 Xcode 链接的框架和库中删除这些依赖项(另请检查大型 ios 项目文件)，仅将 deps 保留在 pod 文件中并运行 pod install .

您可以对每个库逐步尝试这种自动链接，它可能不适用于某些旧库。还要检查您的库版本是否支持自动链接。
