Path for scancode is not found

Hi,

I have just compile and run ort but I have an issue with the scanner:

❯ ~/Software/ort/cli/build/install/ort/bin/ort --info scan -i ./ort/analyzer-result.json -o ./ort/

It looks like /tmp/ort-ScanCode-3.2.1-rc28939431382011693687/scancode-toolkit-3.2.1rc2/bin/scancode does not exist so I looked at the downloaded folder and indeed there is no scancode:

I manage to find it in the previous folder:

The important lines are

ERROR: Could not find a version that satisfies the requirement future>=0.16.0 (from scancode-toolkit==3.2.1rc2->-r /tmp/ort-ScanCode-3.2.1-rc28939431382011693687/scancode-toolkit-3.2.1rc2/etc/conf/requirements_base.txt (line 1)) (from versions: none)

So the bootstrapped ScanCode fails to configure itself, probably due to an unsupported Python version on your side. Indeed, from the paths it seems you're using Python 3.8, which is not yet supported by ScanCode (actually, there several ScanCode issues about the Python version).

Thank you, looks like it works with python 3.6 (its running at the moment).
