React-native构建失败，未定义符号_RCTInjectedAssertFunction

Question

我使用以下工具构建我的项目。

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

但我收到了一个错误。

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)

我做错了什么？构建设置中有什么东西？ enter image description here

Answer 1

尝试此操作，从项目directroy中删除ios，android和node_modeules文件夹。 然后跑， npm install react-native upgrade react-native link

这适合我。
