This seems to be something wrong about your Python installation, not Leo. My Python 3.8 installation in Windows has the exact same line at the same line number (class RegexFlag(enum.IntFlag):) and it works for me.
You could check this as follows: 1. Open a Python3 session. 2. Type the following: import enum enum.IntFlag You should see <enum 'IntFlag'> If you get some kind of an error, you will know for sure it's a problem with your installation.
