@sungbin hi,I also had this problem during installation. Do you have a solution?

[chenzimin]

Maybe this is related to https://github.com/skyhover/Deckard/issues/21?

Looks like a python3 issue to me. If you have python2 still installed (its officially unsupported since Jan/20) you can edit the shebang in src/ptgen/*/main*.py from /usr/bin/env python to /usr/bin/env python2. This worked for me on Arch Linux.

I met the same error on linux(Ubuntu 18.04.2 LTS) as your error on Mac. Did you solve your error on Mac?

As I wrote, it works when you replace python with python2 in the first line of the python files in ptgen

I get this error when building. Can anyone help me with this?

I have solved this problem. This problem is mainly caused by the incompatibility of python2 and python3. The .py files in this project is written by python2, but it calls python3 in your computer during installation. An approach is to change these python2 files into python3 using 2to3.py. 2to3.py is a built-in tool of python. You can use it in Unix-like OS by: 2to3 -w xxx.py. After transforming all python2 files into python3, it can be built successfully.

Another problem is assigning a value to True/False in several files(e.g /src/ptgrn/antlr.py). I just delete the relevent code fragment. I hope this will not cause other problems.
