Everything installed properly.

But when I run:

subprocess32 and functools32 should only be installed on python2.

Any idea why v8.0.1 dod not fix this?

(tried both outside and inside virtualenv).

no, it’s not “running in a virtualenv” in that instance. The environment variables for the virtualenv aren’t set.
