The problem is in the upstream netifaces package and is being tracked at https://github.com/al45tair/netifaces/issues/2. Until that is fixed you can install netifaces without using wheels to avoid this problem.

Something like `pip install --force-reinstall --upgrade --no-binary netifaces`

Hope this helps,
