無法在模擬器中啓動反應原生應用程序

我正在嘗試關注官方react-native tutorial。一切都很好，直到我嘗試運行該項目。然後bash腳本與以下錯誤消息無法在模擬器中啓動反應原生應用程序

~/react_sites/AwesomeProject/node_modules/react-native/packager ~ 

/Users/Chris/react_sites/AwesomeProject/node_modules/react-native/local-cli/cli.js:74 
    const setupEnvScript = /^win/.test(process.platform) 
    ^^^^^

彈出並模擬器給出了Could not connect to development server錯誤。我該如何解決？

我正在使用Xcode 7.2。
