bro you ALREADY HAVE beautifulsoup4-4.9.1-py2-none-any.whl, it is the reason why your exploit script errored out in the first place aaaahhhhhhhhhhhhh
in my original answer i think you need to install beautifulsoup4-4.9.1-py3-none-any.whl, the -py3 one! the -py3 one!
bro i think you need to try pip3 install beautifulsoup4-4.9.1-py3-none-any.whl
specify! 3! wherever! you! can!
including when you run your exploit python3 <exploit>
(pls work)
