How to deploy nodejs code from local machine to google app engine

I have just started with nodejs and app engine. I am following the tutorial

https://cloud.google.com/nodejs/tutorials

1) I have created a project then cloned the nodejs-mvms-quickstart repository.

2) Opened Development/source code and opened the nodejs-mvms-quickstart/1-hello-world

3) and started the node server

npm start

This is working fine. Now I want to deploy my nodejs application from my local server without copying to github and cloning on the server.

For this I am using following command

gcloud app deploy

but this is showing following errors

If this is your first deployment, this may take a while...done.
