Default workflow doesn't work out of box on windows

[theodox]

I tried setting this up on my home machine which is running 3.7.7, but make devserver fails with

 CRITICAL: TypeError: can't pickle generator objects

It might ultimately be this issue: getpelican/pelican#2400

Still investigating... but we should definitely offer a windows workflow that works out of the box

[cmcpasserby]

this is not isolated to windows, just recreated the issue on macOS following the instructions in the readme.md

[JeffHanna]

Can we cast the generator object to a tuple and move on?

[bob-white]

Depending on how it tries to interact with the pickled object yeah, that might be a solution. But if its relying on the data not yet being solidified then it could be wrong.

In the past i've run pelican server's directly with python -m pelican I'll see if I can dig up example code

[VictorStepanov]

@theodox Do the bat files work for you?

Use peldev.bat to generate/auto-reload the website:
start peldev.bat
Use pelserv.bat to start hosting the website locally:
start pelserv.bat

I made them as a workaround for getpelican/pelican#2400

[VictorStepanov]

Or do we want to fix the issue and make a PR for Pelican?

I just installed python 3.7.3 on macOS and I can't reproduce the issue :(

@cmcpasserby What python are you using?

[theodox]

for 3.7 still failing to start the server in the bat file. The site generation appears to work but nobody's listening on the loopback:

I just installed python 3.7.3 on macOS and I can't reproduce the issue :(

@cmcpasserby What python are you using?

was using 3.8

[VictorStepanov]

The fix is to bump Pelican from 4.2.0 to 4.5.0.
I checked on Windows py3.7 and mac py3.8.

Here is the fix
#6

[VictorStepanov]

Did that update resove the issue for you?
@theodox @cmcpasserby

[theodox]

Not yet. Site generates but the dev server still seems to fail silently.

when I ctrl-c

at least now python -m pelican --listen is working, however, though it's not killable from the command line for some reason

[VictorStepanov]

I'm having a hard time reproducing the issue, that you are talking about, on Windows with py37.

Just to make sure we are on the same page.

@theodox
Can you, please, try this script that tries to reproduce the issue?

[VictorStepanov]

I made a wrapper script to guarantee Pelican process termination when you send CTRL+C.
