问题描述

最近升级到Python 3.8，并安装了jupyter.但是，当尝试运行jupyter notebook时，出现以下错误:

Upgraded recently to Python 3.8, and installed jupyter. However, when trying to run jupyter notebook getting the following error:

  File "c:\users\user\appdata\local\programs\python\python38\lib\site-packages\tornado\platform\asyncio.py", line 99, in add_handler
    self.asyncio_loop.add_reader(fd, self._handle_events, fd, IOLoop.READ)
  File "c:\users\user\appdata\local\programs\python\python38\lib\asyncio\events.py", line 501, in add_reader
    raise NotImplementedError
NotImplementedError

我知道Windows上的Python 3.8默认情况下已切换为ProactorEventLoop，因此我怀疑它与此相关.

I know Python 3.8 on windows switched to ProactorEventLoop by default, so I suspect it is related to this.

Jupyter目前不支持Python 3.8?有解决方法吗?

Jupyter does not support Python 3.8 at the moment? Is there a work around?
