【问题描述】：
我正在使用 mkdocs 设置文档，但在运行“mkdocs serve”命令时出现“NotImplementedError”
请注意，我正在使用 Windows 10 并安装了 Python 3.8.0a3 版本

我想知道错误的来源并修复它
【问题讨论】：
-
根据回溯，错误是由
asyncio库引发的，由tornado调用，由livereload调用，由mkdocs调用。问题可能出在该依赖链中的任何地方。我知道 MkDocs 还没有在 Python 3.8 上运行它的测试。我不确定任何依赖项。我的猜测是，您正在使用的 Python 的 alpha 版本破坏了某些东西。但是如果没有大量的调试，我不知道是什么。我会从asyncio开始，然后倒退。 -
根据你的回答，我通过将我的 python 版本降级到 3.7 成功修复了它！
