Trying to install Platformio into VSCode, but it can't find Python, even though it is onboard!

Norman,
I just had a chance to follow your example on my Win 10 machine. I did everthing step-by-step as you wrote, and downloaded the exact files you mentioned. Well, Python 3.8.6 resides happily on my system, and is listed in the path. VSCode loaded and resides happily on my system, right up to where I install PlatformIO.ide. I get the error message “Failed to load PlatformIO”. I give up! lol.

I need this setup to write and modify Marlin firmware for my 3D printers. This is the only task I would ever see myself using. I wish to tap into your knowledge, if you would permit me.

I see a lot of these posts are based on Linux machines, and you yourself mentioned your preference for it. I know nothing about Linux, other than there are a lot of different versions. I grew up on MS-Dos and Windows as a user, but not a programmer. Getting the ability to edit Marlin is vital to me. If I want to set up a very minimal Linux machine solely to run the VSCode and its required components, what would I need? Can I use an old Chromebook or netbook? What Linux version would be best for me? Thanks in advance for any guidance you can provide me.

Tony
