A bug in python 3.7?

[yjqiang]

cannot 'yield from' a coroutine object in a non-coroutine generaorator.

RuntimeWarning: coroutine "BaseEventLoop.create_ connection" was never awaited.

[yjqiang]

try: self.ws = await websockets.connect('wss://broadcastlv.chat.bilibili.com/sub', timeout=3) except: print("# 连接无法建立，请检查本地网络状况") print(sys.exc_info()[0], sys.exc_info()[1]) return False

[yjqiang]

It works well in python 3.6, while crash in python 3.7.

Could you print the python backtrace here ? Thanks

<class 'TypeError'> cannot 'yield from' a coroutine object in a non-coroutine generaorator.

(The code I showed before)RuntimeWarning: coroutine "BaseEventLoop.create_ connection" was never awaited.

[yjqiang]

That is all it shows to me. But you can run the code I gave, and print more information.

These are the concrete codes

You're hiding the backtrace, please remove the try/except and let the full backtrace print on screen, and copy paste that. Thanks

Dupe of #405 then. 3.7 is supported on master - which I encourage you to test - and the next release will include the necessary changes. Closing. Thanks

[yjqiang]

I noticed that once, but couldn't find in a short time, so I thought it is the feature for python3.8. LOL. Anyway thanks a lot.

Version 6.0 adds support for Python 3.7 and is now available on PyPI: https://pypi.org/project/websockets/6.0/#files
