问题
When I try to install the python package Twisted on my windows 10 machine running python3.7, I'm unable to build a Wheel from the .tarz file and I eventually get the following output:

I've tried the following things to resolve this issue:
- Updating Visual Studio build tools 2017
- Updating pip and setuptools
- Installing Windows 10 SDK in Visual studio build tools 2017
- running pip from administrator command prompt
- running pip from Visual Studio x64 Native Tools Command Prompt
- Installing a wheel from this site:https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted which does work but then when I run Scrapy it seems the twisted is an outdated version and there's syntax error with python 3.7
回答1:
Try to install Twisted from this distr, please. This is helps me https://www.lfd.uci.edu/~gohlke/pythonlibs/#twisted
回答2:
Twisted does not yet support Python 3.7. From here:
Twisted does not yet support Python 3.7. Due to syntax changes and other changes, as well as the non-availability of build infrastructure at this moment (e.g. it doesn't work on Travis, we haven't tried appveyor), we can't yet fully identify what's wrong and fix it with confidence.
You can track their progress towards Python 3.7 support here.
