环境

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

在运行应用程序之前我做了什么

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

我是React Native的新手.当我尝试在iOS模拟器上运行默认应用程序时,我收到以下错误.我发现了类似的问题,但它并没有解决我的问题.

Xcode6无法在模拟器中运行任何应用程序(Domain = NSPOSIXErrorDomain,Code = 3)

重启机器和模拟器后问题仍然存在.

我正在尝试使用React Native启动并运行,我在Xcode中看到以下消息:

端口8081已在使用中,打包程序未运行或未正常运行

命令/ bin/sh失败,退出代码为2

我去了React Native故障排除页面并尝试终止端口8081进程,但我仍然遇到同样的问题.

这是我在Xcode中看到的截图:

任何帮助将完全赞赏.
