I'm trying to package my wxPython application, but facing the following error when trying to execute it:

Traceback (most recent call last):

2020-11-29 12:10:31.929 kosmorro[4138:95553] Kosmorro Error

My setup.py:

#!/usr/bin/env python3

from setuptools import setup

APP = ['kosmorro-gui']
DATA_FILES = []
OPTIONS = {
    'plist': 'build/distrib/darwin/Info.plist',
    'packages': ','.join(['skyfield>=1.21.0,<2.0.0', 'tabulate', 'numpy>=1.17.0,<2.0.0',
                          'termcolor', 'python-dateutil', 'wx'])
}

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

My kosmorro-gui:

#!/usr/bin/python3

from kosmorrolib.gui import mainwindow

def main():
    mainwindow.start()

if __name__ == '__main__':
    main()

kosmorrolib is a package included in my app. If needed, the mainwindow module can be found here.

I'm running macOS 11.0.1 and Python 3.9.0

What does this error mean, and how can I fix it?

I'd like to know the answer to this one also.

I'll see if I can reproduce this locally.

How did you install Python and wxPython (python.org installer, homebrew, ...)?

[hasii2011]

For me I use pyenv from homebrew; Then create a virtual environment like

python3 -m venv venv-pyenv-3.9.0 and 
source ./venv-pyenv-3.9.0/bin/activate
pip3 install wxpython

the latest stable wxpython

[Deuchnord]

On my side, it is installed globally with PIP:

pip install -g wxPython

Hi @ronaldoussoren, did you manage to reproduce the error, or do you need more information? 🙂

If needed, I wrote a reproducer that opens an empty window: https://github.com/Deuchnord/py2app-wx-issue-bad-rebase-reproducer

When invoked with python3 app.py, the empty window opens as expected. But when the app is built, the app fails opening.
