Hi!

I get the above error when I try to import the parse function as indicated in the docs:

>>> from boolean_parser import parse

Traceback:

The error is gone after downgrading sqlalchemy from v1.4.15 to v1.3.13.

Thanks @muxevola. Yeah I haven't been able to fully test it against sqlalchemy 1.4 but I guess I should since that's the default that will get installed. I will try to update to 1.4 but if if not, I'll pin the dependency req.

Closing this. This was fixed in #4 .
