tornado#

tornado 使用 WindowsSelectorEventLoopPolicy() 报错(Windows)#

或者报:in add_reader raise NotImplementedError NotImplementedError

参考 Prepare for python 3.8 on windows · Issue #2608 · tornadoweb/tornado (github.com)

处理方法:在 C:\Users\用户名\conda 路径\Lib\site-packages\tornado\platform\asyncio.py 中添加如下代码:

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