React Native - 无法构建DependencyGraph:无法读取null的属性"root"

Question

我试图让React Native第一次运行他们的hello world应用程序(AwesomeProject),我在控制台中收到此错误:

Failed to build DependencyGraph: Cannot read property 'root' of null TypeError: Cannot read property 'root' of null at index.js:16:60 at tryCallOne (/Users/Eduardo/Documents/Code/Personal/ReactNative/AwesomeProject/node_modules/promise/lib/core.js:37:12) at /Users/Eduardo/Documents/Code/Personal/ReactNative/AwesomeProject/node_modules/promise/lib/core.js:123:15 at flush (/Users/Eduardo/Documents/Code/Personal/ReactNative/AwesomeProject/node_modules/asap/raw.js:50:29) at _combinedTickCallback (node.js:370:9) at process._tickCallback (node.js:401:11) ~ Process terminated. Press <enter> to close the window

首先,我是一个移动开发人员(本机ios和android),我知道关于节点的小队.

我按照React Native 的Getting Started页面,用npm install和安装了npmnpm install -g

当我尝试单独启动节点服务器时,node server我得到了这个:

$ node server
module.js:341
throw err;
^

Error: Cannot find module '/Users/Eduardo/Documents/Code/Personal    /ReactNative/AwesomeProject/server'
at Function.Module._resolveFilename (module.js:339:15)
at Function.Module._load (module.js:290:25)
at Function.Module.runMain (module.js:447:10)
at startup (node.js:141:18)
at node.js:933:3`

这是我在iOS模拟器中获得的屏幕截图,以及尝试运行应用程序时的控制台:

值得一提的是,我在使用Xcode 7.2的Mac OS 10.10.5上运行它,而NativeScript创建了一个简单的应用程序而没有任何问题.

关于如何做的任何建议？

我目前只是想用React Native弄湿我的脚.谢谢!
