Answer 1

I stumbled upon the question when I was googling about `ERROR: Could not install packages due to an OSError: [WinError 2] The system cannot find the file specified`.
In my case, VS Code by default tried to install the linter on the python installed via It choco
& C:/Python310/python.exe -m pip install -U flake8
looked like a permissions problem, and yes, manually with the command

& C:/Python310/python.exe -m pip install -U flake8 --user

everything was set up very well.
