[Twisted-Python] Installing Twisted on a clean Windows system
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
I installed the compiler package indicated here: https://wiki.python.org/moin/WindowsCompilers (section titled "Microsoft Visual C++ 14.0 standalone: Build Tools for Visual Studio 2017 (x86, x64, ARM, ARM64)") and get a bunch of this: d:\programs\python37\include\pystate.h(209): note: see declaration of '_ts' src/twisted/internet/iocpreactor/iocpsupport/iocpsupport.c(7699): error C2039: 'exc_traceback': is not a member of '_ts' d:\programs\python37\include\pystate.h(209): note: see declaration of '_ts' src/twisted/internet/iocpreactor/iocpsupport/iocpsupport.c(7700): error C2039: 'exc_type': is n ot a member of '_ts' d:\programs\python37\include\pystate.h(209): note: see declaration of '_ts' src/twisted/internet/iocpreactor/iocpsupport/iocpsupport.c(7701): error C2039: 'exc_value': is not a member of '_ts' d:\programs\python37\include\pystate.h(209): note: see declaration of '_ts' src/twisted/internet/iocpreactor/iocpsupport/iocpsupport.c(7702): error C2039: 'exc_traceback': is not a member of '_ts' d:\programs\python37\include\pystate.h(209): note: see declaration of '_ts' error: command 'D:\\Programs\\VS\\VC\\Tools\\MSVC\\14.14.26428\\bin\\HostX86\\x64\\cl.exe' fail ed with exit status 2 (there was more but this is the gist of it). Really strongly pointing back at Python 3.7 at this point but it's not where I usually live so ... Regards, Jeff On Sun, Jul 1, 2018 at 10:53 AM Jeff Grimmett <grimmtooth@gmail.com> wrote:

Aaaand, installed Python 3.6.6 and pip install'd Twisted 18.4.0 without any problems. So much for getting those sweet performance improvements in 3.7 for now - Twisted is an absolute requirement, 3.7 is not. Anyways, looks like there's a compatibility issue between 3.7 and Twisted on Windows at this point. Anything I can to do assist in troublshooting, lmk. I'll be glad to help if I can do it. I'm completely lost in the woods where this kind of stuff is concerned. Regards, Jeff On Sun, Jul 1, 2018 at 11:19 AM Jeff Grimmett <grimmtooth@gmail.com> wrote:

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. -Amber Twisted Release Manager On Sun, 1 Jul 2018, 15:53 Jeff Grimmett, <grimmtooth@gmail.com> wrote:

Thanks for the confirmation, Amber. Settling down with 3.6.6 install. Regards, Jeff On Sun, Jul 1, 2018 at 12:13 PM Amber Brown <hawkowl@atleastfornow.net> wrote:
