React-native構建失敗，未定義符號_RCTInjectedAssertFunction

Question

我使用以下工具構建我的項目。

react-native-cli: 2.0.1 
react-native: 0.41.2 
XCode Version 8.2.1 (8C1002) 

但是我得到了一個錯誤。

Undefined symbols for architecture arm64: 
    "_RCTInjectedAssertFunction", referenced from: 
     -[RCTWebSocketExecutor executeJSCall:method:arguments:callback:] in libRCTWebSocketDebugger.a(RCTWebSocketExecutor.o) 
     -[RCTWebSocketExecutor dealloc] in libRCTWebSocketDebugger.a(RCTWebSocketExecutor.o) 
    "__RCTLogFormat", referenced from: 
     -[RCTWebSocketExecutor initWithURL:] in libRCTWebSocketDebugger.a(RCTWebSocketExecutor.o) 
     -[RCTWebSocketExecutor webSocket:didFailWithError:] in libRCTWebSocketDebugger.a(RCTWebSocketExecutor.o) 
ld: symbol(s) not found for architecture arm64 
clang: error: linker command failed with exit code 1 (use -v to see invocation) 

我在做什麼錯？在構建設置中的東西？ enter image description here

試試這個，從項目directroy刪除ios，android和node_modeules文件夾。 然後運行， npm install react-native upgrade react-native link

這對我的作品。
