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.

I would suggest sticking with 3.6 until at least 3.7.1 rolls around, by which time it's likely that Twisted and other projects have had time to catch up.

I am attempting to install Twisted 18.4.0 on a clean system, fresh install of Python 3.7. When I attempt to install from the source dist (python setup.py install) it complains I don't have the MS Visual C++ Build tools ("error: Microsoft Visual C++ 14.0 is required. Get it with "Microsoft Visual C++ Build Tools"") and directs me to http://landinghub.visualstudio.com/visual-cpp-build-tools - which is a 404.

"pip install twisted[windows_platform]" fails for the same reason.

Not sure where to go for a good compiler here ... any ideas? Is it too soon to adopt Python 3.7? Should I go back to 3.6? (this is going to be a system install so I'd prefer to avoid all virtualenv entanglements)

TIA,

Jeff
