Error: Cannot find module 'archiver'

If any of you remember my previous thread, I am having this issue since a long time. I thought it was something isolated and only I am facing it. But a Google search throwed a lot of results including Github issues reported on Ionic as " not all dependencies installed ". But I could not find a solution in any of those reported issues. Any chance I can fix it with your help ?

PS : Using Ubuntu 14.04

Ref :

Ref 1 : Unable to make Ionic work in Ubuntu 14.04

Ref 2 : A guide to install Ionic 2 in Ubuntu 14.04

This is the full error I get

ionic start myApp1 blank
    throw err;

No one ? :frowning:

I could do with a bit of help on this.

I am sorry to bump. But I could really do with some help.
