Ubuntu 20.10. Python3 v 3.8.6 and Python 2.7.18.
Platformio 2.2.1 on vscode:
Error: Python 3.6 or later is required for this operation. Please check a
migration guide:
The convention on linux is that python is a symlink to python2 when both are installed, and python3 is a symlink to python3. Vscode/Platformio keeps finding 2. Is there a platformio specific setting for this??? I have other stuff that needs python2, and telling me to change the symlink will just move the problem to others’ backyards.
In the VSCode settings for python, theres a “default interpreter path” option, you should be able to set the python3 path there.

That didnt work. I set it everywhere I could find
Right then, It should be using it if you have configured it. What do you get if you open a terminal inside VSCode (from the menubar) and type python --version? I would expect the one you configured.
Close that terminal.
if you got 3.x, open the PlatformIO terminal next, left side, click ant/alien head icon, look for an option to open a terminal.
Execute python --version again. Same result? Wrong?
There’s a PlatformIO option to use a portable python interpreter:
Platformio-ide: Use Builtin Python
“Use a portable python 3 interpreter if available” – if you tick/check that, it will use the python 3 interpreter that it downloaded into ~/.platformio/penv/bin.
There are three pythons there, python, python3 and python3x - they are symlinks to either the system wide python3 interpreter, or, to the downloaded python3 interpreter as appropriate.
~/.platformio/penv/bin/python --version should give you a 3.x version and using the “portable” interpreter in VSCode should also give the same version – if the option has “stuck”.
Cheers,
Norm.
You may also just try and install it locally per docs. When you reinstall the VSCode PlatformIO extension, it should automatically pick up the existing core.
I just downloaded a clean Ubuntu 20.10 ISO image and started a virtual machine with it and installed it. I fully updated the installation with sudo apt update && sudo apt upgrade. Then installed VSCode from the .deb file.
First installation of PlatformIO gives
which tellls you to sudo apt install python3-distutils.
After doing that and a VSCode restart, it begins to install the PlatformIO core. Which works

So I can just recommend to update all packages and try with a clean VSCode installation, from the .deb. (not the snap or anything else)
