React Native iOS构建失败：架构x86_64的未定义符号 [英] React Native iOS build failed : Undefined symbols for architecture x86_64

问题描述

我正在使用React Native构建一个iOS应用。这样做，我安装了

其中 MedwayTwilio是我的项目名称

解决方案

您是否按照 ？

此外，您还需要添加依赖项

  pod'React'，：path =>上的RCTBatchedBridge子规范（如果使用0.46）或RCTCxxBridge（如果使用较新）。 ‘../node_modules/react-native’，：subspecs => [
'Core'，
'DevSupport'，＃如果RN> = 0.43 
 [...] 
'BatchedBridge'，＃包括此项以启用应用内开发菜单如果RN = 0.46 
'CxxBridge'＃包括如果RN> = 0.47 
] 
  

I'm building an iOS app with React Native. Doing so, I installed a react-native module and configured my iOS xcode project (cocoapods mainly) following the module tutorial. Now, when I run react-native run-ios, I get this error stack :

Undefined symbols for architecture x86_64:

ld: symbol(s) not found for architecture x86_64

clang: error: linker command failed with exit code 1 (use -v to see invocation)

** 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)

I suspect this is related to the inclusion of libraries and frameworks to the project with xcode, but I'm not sure.

This is a screenshot of my project target/build phases/link binary with libraries panel in xcode :

Where "MedwayTwilio" is my project name

解决方案

Did you configured your CocoaPods dependencies as described in the documentation?

Also, you need to add a dependency on the RCTBatchedBridge subspec (if using 0.46) or RCTCxxBridge (if newer).

  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
  ]
