py2app - IndexError: tuple index out of range

Getting the following error when trying to build my application. My code runs smoothly inside VScode (running the python file directly). I've looked online and I can't seem to find anyone who's had this error pop up. It used to happen to me when I wasn't in my virtual environment, but I definitely am now (source venv/bin/activate). What could it be? Thanks

I use the default setup.py using the command provided in the docs py2applet --make-setup bot.py

"""
This is a setup.py script generated by py2applet

Usage:
    python setup.py py2app
"""

from setuptools import setup

APP = ["bot.py"]
DATA_FILES = []
OPTIONS = {}

setup(
    app=APP,
    data_files=DATA_FILES,
    options={"py2app": OPTIONS},
    setup_requires=["py2app"],
)
Solution

  • The problem is that you have installed a beta version of Python (version 3.11). And looks like py2app version 0.28.2 is not compatible with it. Try to uninstall the 3.11 version and install the current release version 3.10 and it should work. Also, recreate the virtual environment after you install it because the current one would still be pointing to the 3.11 version.
