hypercorn not working on Windows 10 ? about hypercorn

[stonebig]

hum, I see some maybe hope there, but not expert in the thing:
encode/uvicorn#423

[pgjones]

Hmm, this used to be an AttributeError, I think Python 3.8 has changed the effective error. Fixed in a8ba7f6. You should be able to use Hypercorn with Python 3.7 without this issue.

[stonebig]

maybe for some under Anaconda, but it doesn't work either on my Python-3.7.
... I'll wait to see uvicorn/hypercorn next releases, I hoped it was something obvious.

so I can get today uvicorn working on Python-3.7 and Python-3.8. I don't catch what detail I have wrong with hypercorn.

[stonebig]

well, with hypercorn-0.9.0dev master it works now on Python-3.8. Thanks a lot !

[pgjones]

Great, thanks for confirming.

having this exact problem with python 3.7.5 x64, any idea how to fix this?

@ghostzero192 If you make use of the master branch it will work, specifically a8ba7f6.

[ghostzero192]

thank you so much, it works perfectly!!

@ghostzero192 Is it just Python 3.7 -> 3.8 that changed (between the working and not working versions)?

[ghostzero192]

@pgjones
in python 3.7 everything works fine if i use the branch that you recomended me (0.9.0+dev), but in python 3.8 neither the master branch (i mean "pip install hypercorn") or the 0.9.0+dev work

[pgjones]

@ghostzero192 I think this is fixed with 0.9.2, see 42c2f6f
