Getting 'npm start' error when trying to build React Native app on iphone?

When I do a build to my iphone 6 I get the following error on my device with the red screen:

"Could not connect to development server. Ensure node server is running - run 'npm start' from React root

The operation couldn't be completed.
(NSURLErrorDomain error - 1004)"

And im getting the following error in terminal in the React Packager:

"Unhandled rejection Error: ENOENT, open '/Users/rahulsharma/Desktop/rcapp/.git/index.lock'"

Lastly, I am getting this in the xcode console:

2015-05-06 12:37:48.631 rcapp[808:262187] CLTilesManagerClient: XPC_ERROR_CONNECTION_INVALID!

Any ideas?

here is the code in git:
