NotImplementedError on Windows about aiodns

In user code, it can be solved by adding

if sys.platform == 'win32':
	asyncio.set_event_loop_policy(asyncio.WindowsSelectorEventLoopPolicy())

Maybe it should be part of the example?

Okay, thanks. By the way, I made an improvement to let other users know about this issue, and merge it if you think it's good. #105

Having the same problem on windows. So the workaround would be to run this under WSL.

Same problem in CPython3.9 on windows10.

Exactly the same problem on Python 3.9.4 on Windows 10 using the example program. Any suggestions?

[FredericMa]

I'm having the same issue.

Still got problem on Windows 10 with python3.9.5 and Windows 11 with python 3.10

c-ares, what is used underneath, requires a readyness style API, which is not supported on Windows unless you are using a SelectorEventLoop implementation: https://docs.python.org/3/library/asyncio-eventloop.html#asyncio.SelectorEventLoop

[saghul]

Oh that's nice! When did they add to Python?

Happy to take a PR if you're up for it!

WindowsSelectorEventLoopPolicy was added in 3.7

In 3.8 the default event loop for windows was changed to ProactorEventLoop. At which point this became necessary.

Seems this was already discussed in #78
