React Native - Failed to build DependencyGraph:Cannot read property 'root' of null

I'm trying to get React Native to run their hello world app (AwesomeProject) for the first time, and I'm getting this error in the console:

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

First of all I'm a mobile developer (native ios and android) and I know squad about node.

I followed the Getting Started page of React Native, got npm installed with npm install and npm install -g

When I try to start the node server alone, with node server I get this:

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

Error: Cannot find module '/Users/Eduardo/Documents/Code/Personal    /ReactNative/AwesomeProject/server'

at Function.Module.runMain (module.js:447:10)
at startup (node.js:141:18)
at node.js:933:3`

Here's a screenshot of what I get in the iOS emulator, and the console when trying to run the app:

For what's worth, I'm running this on a Mac OS 10.10.5 with Xcode 7.2, and NativeScript creates a simple app without issues.

Any suggestions on what to do on this?

I currently just want to get my feet wet with React Native. Thanks!
