Can't make it work on Windows

Hi!

I managed to install beets without errors, but when I type "beet" on the console, instead of a list of commands this message appears:

Traceback (most recent call last):
  File "C:\Python39\Scripts\beet-script.py", line 33, in <module>
    sys.exit(load_entry_point('beets==1.4.9', 'console_scripts', 'beet')())

    _raw_main(args)

    prog = compile(mod, '<generated>', 'exec')
ValueError: Name node can't be used with 'None' constant

What went wrong? I reinstalled it multiple times and the same problem appeared every time

btw I'm using Python's latest version (3.9.6) instead of  the 3.6 that the documentation recommends, could that be the problem?

Thanks!

I have the exact same issue, also on Python 3.9.6
