My meanjs Application is not getting started in offline mode?

Question

I have installed all the prerequisites for a mean application(MEAN) as described in Meanjs Official website

I want you to look at this particular error I am getting and that too when I am offline. But it does work well when I am connected to internet. Help me Try looking at the error below:
