solutions

Scrapy can work with Python 3 on windows if you make some minor adjustments:
Copy the _win32stdio and _pollingfile to the appropriate directory under site-packages. Namely, twisted-dir\internet. Download these fromhttps://github.com/twisted/twisted/tree/trunk/twisted/internet
 URLS: https://github.com/twisted/twisted/blob/trunk/src/twisted/internet/_win32stdio.py
URLS: https://github.com/twisted/twisted/blob/trunk/src/twisted/internet/_pollingfile.py
pip install pypiwin32
Granted, this is based on my personal experience. Because the repository will certainly change in the future, readers should beware the age of this answer.
