"npm warn deprecated" when executing "npm install -g @hubspot/cli"

Hi guys!
I am receiving these warning every time I run this command :
npm install -g @hubspot/cli
I even tried running this command :
npm install -g @hubspot/cli@latest


npm warn deprecated
I also tried running : npm update
> result : creation of “package-lock.json” file > empty like shown below

Any clues on how to solve this ?
Thanks!!
