Unable to install cottonballs

[strongbull1]

I was trying to install “cottonballs” for a similar testing, however I see the following errors.
Do you have any insight as to what might be happening ? from the look of it, it feels like the Code is old and using some old functions which are deprecated ?

Appreciate if you could help

(node) sys is deprecated. Use util instead.
