Can't install jsonlib with pip

Due to Error 1 (below) I've downloaded an installer via the URL at the last line of the error. "Visual Studio Build Tools 2022 - 17.4.4" window has popped up with many options of things to install so I just choose "C++" as it said.

Then when I try run 'pip install jsonlib' again, I get error 2 (below again). I googled "exit code 1120" and it says something about linker and no need to fix error as it goes away...

I've tried restarting after installing windows c++ VS build tools and re-opened cmd.

Someone linked to this python page on another stack but no further explanation and I'm not sure what it means https://wiki.python.org/moin/WindowsCompilers
