cannot use python3.6 in buildInputs

[permahorse]

you can test on simple

mkShell {
    buildInputs = [ nixpkgs-python.packages.x86_64-linux."3.6" ];
};

then with nix develop - python will not start. looks like the problem has something to do with this change since 3.8

What error do you get?

sorry that i haven't posted the error message - thought it's easier to reproduce and see, but here it is:

ModuleNotFoundError: No module named '_sysconfigdata__linux_x86_64-linux-gnu'

as you see, there is m missing in '_sysconfigdata__linux_x86_64-linux-gnu' and that has something to do with this i bet

Someone should try to apply https://github.com/pypa/distutils/pull/111/files and see if it fixes it.
