I'm using Python 3.9 on a Mac running Big Sur and am trying to create an
app, MyApplication.app, from a script using py2app. I'm following the
process outlined at https://py2app.readthedocs.io/en/latest/tutorial.html .
The app itself uses tkinter for creating a GUI. My setup file looks like
the following, where 'background.png' is an image that appears on the
screen at program startup, and 'pandas' and 'cmath' are included due to
previous error messages:
from setuptools import setup
APP = ['MyApplication_6_14.py']
DATA_FILES = []
OPTIONS = {'resources':['background.png'],'packages': ['pandas','cmath']}
setup(
app=APP,
data_files=DATA_FILES,
options={'py2app': OPTIONS},
setup_requires=['py2app'],
)
I can create and run the application in alias mode, and no error messages
arise when I build for deployment. However, when I attempt to run the
deployed version from the command line via,
./dist/MyApplication.app/Contents/MacOS/MyApplication
I receive a fairly lengthy error message below, where Python_May_2021 is
the file location:
fishbacp@fishbacpK0ML85 Python_May_2021 %

I'm curious to know if anyone has insights regarding the last line in the
above message.
Thanks
