linker command failed in react native app, using react-native-firebase
提问by Razvan Bretoiu
I developed a react native app using react-native-firebase library.
I want to set my app icon, so I used this library:npm install -g yo generator-rn-toolboxfrom here.
我使用 react-native-firebase 库开发了一个 React Native 应用程序。我想设置我的应用程序图标，所以我使用了这个库：npm install -g yo generator-rn-toolbox从这里开始。
When I try to build the project I receive this error:
当我尝试构建项目时，我收到此错误：
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_RCTSRWebSocket", referenced from:
objc-class-ref in libReact.a(RCTInspectorPackagerConnection.o)
"_OBJC_CLASS_$_RCTReconnectingWebSocket", referenced from:
objc-class-ref in libReact.a(RCTPackagerConnection.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
How do I fix this ?

I fixed it by manually adding the RCTWebsocket library:
我通过手动添加 RCTWebsocket 库来修复它：
- find the RCTWebsocket project:
open -R node_modules/react-native/Libraries/WebSocket/RCTWebSocket.xcodeproj - Drag it into xcode under your projects Libraries folder
- on your project, select your project target, then goto "Build phases" --> "Link Binaries With Libraries" --> "+"
- Search for
libRCTWebSocket.aand add it
- 找到 RCTWebsocket 项目：
open -R node_modules/react-native/Libraries/WebSocket/RCTWebSocket.xcodeproj - 将其拖到项目库文件夹下的 xcode 中
- 在您的项目中，选择您的项目目标，然后转到“构建阶段”-->“将二进制文件与库链接”-->“+”
- 搜索
libRCTWebSocket.a并添加
your project should build now. If libRCTWebSocket.ain step 4 is not there, try to build the project first.
您的项目现在应该构建。如果libRCTWebSocket.a第 4 步中没有，请尝试先构建项目。

I had the similar issue for iOS 12, XCode 10.
For those that may help (and avoid losing days like me..),
i had to add the libRCTWebSocket.aand the libfishhook.abinaries in the YourProject -> Targets -> YourProject -> Link Binary With Librarieslist
我在 iOS 12、XCode 10 上遇到了类似的问题。对于那些可能有帮助的人（并避免像我一样浪费时间..），我必须在 YourProject -> Targets -> YourProject -> list 中添加libRCTWebSocket.a和libfishhook.a二进制文件Link Binary With Libraries
回答by Build3r
I was able to build the app by placing libRCTWebSocket.a before libReact.
我能够通过在 libReact 之前放置 libRCTWebSocket.a 来构建应用程序。
