Building error

Hi , I got this error when running build.sh:

it seemed that YaccParser.py assigned to False, which is not accepted in python.
Did I have the wrong environment or something went wrong ?

Seems you have syntax error in the YaccParser.py file written in Python 2 syntax. In that case, you may need to update the Python scripts in the Deckard project to be compatible with Python 3, as they all seem to be written in Python 2 syntax. To do this, you can use the 2to3 tool that comes with Python 3 installations.

thanks!
I tried 2to3.py but it still has an error:

Is it about the version error of bison and flex? Should I use lower version?
