With Python 3.11 I got this error,

re.error: global flags not at the start of the expression at position 63

Same issue for me on 3.11. Switched to 3.9 and it's working.

The best approach would be to offer this program as a docker which would solve all future dependency issues and provide a "simply works" solution.

Sorry @all I will try to update the code. @oregonpillow PR is welcome to dockerize this utility. @rabin-io hopefully the issue resolved with your PR. Sorry for the delayed responnse
