Cannot install Scancode from source on Python 3.8.x

[pombredanne]

There are issues reported where url.py cannot be recompiled and our url.py dependency is incorrect

Hi @pombredanne ,are you referring to the url wheels in the thirdparty directory which is not compatible with Py3.8?

I can confirm that installing on Python 3.8 doesn't work at all, and the first failure encountered is because url<1.0.0,>=0.4.2 picks up the sdist-only release at https://pypi.org/project/url/0.4.2/, which in turn includes old Cython generated code that accesses fields that are no longer public in Python 3.8+.

Other reports: seomoz/url-py#67

I tried installing current git develop branch instead:

pipenv install git+https://github.com/nexB/scancode-toolkit.git@72850bd5#egg=scancode-toolkit

However, that still failed, as the dependency on url.py is still declared in develop - the switch to urlpy hasn't been merged yet.

I'm now trying the tip of #1835 instead.

This version installed (tip of #1835 at time of writing):

pipenv install git+https://github.com/nexB/scancode-toolkit.git@10f54bf#egg=scancode-toolkit

Thanks to all who contributed to this issue. It would be great to have a release containing the fix. :)

@antgel It is coming :) I am furiously merging branches at the moment and should tag a release either today or tomorrow !
Thank you for your patience!

@antgel note that you should be able to use the tip of the develop branch alright in the meantime
