Can't setup QMK in MacOS Big Sur

[zk2004mb]

After installation in brew, the QMK can't be called.
Here is the error info:

(base) xxxxx@xxxxxx-iMac-Pro ~ % qmk
Error: %s: %s ('ImportError', ImportError("cannot import name 'format_ansi' from 'milc' (/usr/local/Cellar/qmk/0.0.45/libexec/lib/python3.9/site-packages/milc/init.py)"))

System: MacOS Big Sur 11.2.1

Also when I check the milc package, it seems format_ansi has been removed.

Version 1.3.0
You can now set the program version number with os.environ['MILC_APP_VERSION'] = '1.2.3'
New global arguments: –unicode and –no-unicode
ANSIFormatter, ANSIStrippingFormatter, ANSIEmojiLoglevelFormatter, and ANSIStrippingEmojiLoglevelFormatter have been removed in favor of format_ansi() being color aware. The new MILCFormatter is being used in its place.

How should I deal with this?

Your qmk_firmware directory probably is out of date.
Try renaming it and run qmk again. If that works you're probably just behind on upstream.

Thank you! It worked.
