Ambiente

Mac OS X Version 10.11.3 (15D21)
Xcode Version 7.2 (7C68)
Simulator Version 9.2 (SimulatorApp-643)
react-native-cli 0.1.10
node v5.5.0

Lo que hice antes de ejecutar la aplicación

npm install -g react-native-cli
react-native init DemoProjectDELETEME
cd ./DemoProjectDELETEME
react-native run-ios

Soy nuevo enReaccionar nativo. Cuando intento ejecutar la aplicación predeterminada en el simulador de iOS, recibo los siguientes errores. Encontré un problema similar pero no resuelve mi problema.

Xcode6 no puede ejecutar ninguna aplicación en el simulador (Dominio = NSPOSIXErrorDomain, Código = 3)

Después de reiniciar la máquina y el simulador, los problemas persisten.

Recibí el error de seguidor cuando intento iniciar la aplicación desde Xcode.

sudo npm start en la raíz del proyecto resuelve el problema, peroreact-native run-ios todavíaCONSTRUCCIÓN FALLIDA.

Gracias por su tiempo viendo mi pregunta.
