关于你遇到的“module 'asyncio' has no attribute 'create_task'”错误,我们可以从以下几个方面进行排查和解决: 确认Python版本是否支持asyncio.create_task: asyncio.create_task函数是在Python 3.7中引入的。如果你的Python版本低于3.7,那么你将无法使用这个函数。你可以通过运行
The create_task top-level function was added in Python 3.7, if you use python 3.6 you should have a issue. "creat_task" was only available as a method (in 3.6) so you can invoke it like: dirrec.py 83 tasks.append(asyncio.get_event_loop()...

AttributeError:'coroutine'object has no attribute'next'sys:1: RuntimeWarning: coroutine'download_url'was never awaited 原生协程async代码中间是不能在使用yield生成器的,这样就为了更好的将原生协程与生成器严格区分开来。并且await只能和async语句搭配,不能和生成器搭配。因为要调用await需要调用对象实现__await...

I think the cause may be that the asyncio maintainers have been messing with their internal api - for example, what used to be called Task._Task__step seems to have been renamed first to Task._step and then again to Task.__step. My company's python3.6 kernel works fine with nest_as...
