npm.w i @werm-fw/cloud @werm-fw/set-up

arg $1 is suppose to be “@werm-fw/cloud” and $2 “@werm-fw/set-up”

but after I want to pass both args as a single string

set -- --packages "$@";

you would think that if i do this im good, but actually I have to do execute the code below for it to work

set -- --packages "$*";
