我正在使用 React Native 构建一个 iOS 应用程序。这样做，我安装了 react-native module并按照模块教程配置了我的 iOS xcode 项目(主要是 cocoapods)。现在，当我运行 react-native run-ios ，我得到这个错误堆栈:
Undefined symbols for architecture x86_64:

** BUILD FAILED **
The following build commands failed:
Ld /Users/antoine/R/devlab/ReactNative/medway-twilio/MedwayTwilio/ios/build/Build/Products/Debug-iphonesimulator/React/React.framework/React normal x86_64 (1 failure)
我怀疑这与使用 xcode 将库和框架包含到项目中有关，但我不确定。
这是我的项目目标/构建阶段/链接二进制文件与 xcode 中的库面板的屏幕截图:
“MedwayTwilio”是我的项目名称
最佳答案
您是否按照 in the documentation 的描述配置了 CocoaPods 依赖项？ ?
此外，您需要添加对 RCTBatchedBridge 子规范(如果使用 0.46)或 RCTCxxBridge(如果更新)的依赖。
pod 'React', :path => '../node_modules/react-native', :subspecs => [
'Core',
'DevSupport', # Include this to enable In-App Devmenu if RN >= 0.43
[...]
'BatchedBridge', # Include if RN = 0.46
'CxxBridge' # Include if RN >= 0.47
]
