Cannot find module 'babel/polyfill' at ionic serve command

When I run my Ionic project in my workstation with “ionic serve” command I receive an error telling me that “babel/polyfill” was not found. I’m trying to make live changes and due to this error I can’t do.

This is the trace:

C:\Users\Admin\Desktop\ionic\ionic-project-1>ionic serve

Ionic server commands, enter:
restart or r to restart the client app from the root

quit or q to shutdown the server and exit

I have installed bower and many Gulp dependencies. How am I doing wrong?
