Error when creating new project with Angular-CLI 6.1.2

Don't use _ (underscore) sign, use minus - (minus) sign.

For Example:

Wrong code:

ng new naytiv_admin_fe

Right code:

ng new naytiv-admin-fe

Melchia is correct.

But to be more specific, the problem is the lone number between the dashes.

This will also work:

ng new angular6-boilerplate

Do not include project name special characters or numbers. Try the following:

$ ng new angular-boilerplate

I did some research & found out that this comes from the schema responsible of creating new Angular applications Link Here

No Snakecase.

Watch out for underscores as well (not just lone numbers).

ng new my_fantastic_app

Is an invalid name.

And of course as other people have already say , be careful for Lone numbers between dashes
