I am setting up a documentation using mkdocs but I am getting "NotImplementedError" when runing the "mkdocs serve" command
Note that I am working on windows 10 and installed the Python 3.8.0a3 version

I would like to get where the error come from and fix it
asynciolibrary, which is called bytornado, which is called bylivereloadwhich is called bymkdocs. The problem could be anywhere in that chain of dependencies. I know MkDocs does not yet run its tests on Python 3.8. I'm not sure about any of the dependencies. My guess is that something is broken by the alpha version of Python you are using. But without a lot of debugging I don't know what. I'd start withasyncioand work my way backwards.
