Werkzeug 0.11.11 not compatible with windows + python 3.6

[cleemesser]

It appears that python 3.6 eliminates socketserver.ForkingMixIn on platforms like windows which do not support the forking model. There is a fix for this in version 0.11.15. I am using werkzeug version 0.12.2 and it seems ok with python 3.6.1 on windows 10 pro.

see:
pallets/werkzeug#999

Thanks for this report. Can you run make test with werkzeug 0.12.2 on Win 10 and confirm that all tests pass? I would like to update this requirement and push that globally.

Unfortunately, I have not succeeded in running these tests. It is tough to get the test harness working on windows (anaconda distribution). mr.bob does not install due to some character encoding problem.

I have tried running each line of the Makefile by hand:
I can create skeletons using cygwin + python 2.7 + pip2 install mr.bob. But then I have trouble getting the test app to pick up the correct configuration. :-(

I get::

Thanks for updating this ticket!

I'm looking at the error log you posted and I think we can debug this. Where it says

FileNotFoundError: [Errno 2] Unable to load configuration file (No such file or directory):

'C:\Users\chris\code\flask-diamond\flask_diamond\flask_diamond\tests\testing.conf'

it means somehow, your SETTINGS environment variable isn't pointing to the right config file. It could be that the Makefile is setting this incorrectly. If you look at the test: or test-win Makefile targets, I am curious to know if the configuration file looks correct.

A configuration file is generated for each project by the scaffolding process - and I would expect the test harness to point towards a config file called etc/conf/testing.conf - but I could be misremembering.
