If you're on an actual Ubuntu desktop, then "perl -v" gives the answer you're looking for. Strawberry is a distribution of perl for Windows, which is what I think most people assumed when you said VSCode.

(this conversation will likely now chain into "don't use the system perl for development, use perlbrew" or something like that. I'd recommend just using system perl until you have everything working, then consider installing your own with perlbrew)
