I cannot duplicate what you are doing.

I have Xcode installed so when I  double click a .py file it ends up in the Xcode editor.

Unless you have written a GUI app then your python program is expecting to be run from a Terminal window.

I'm guessing what what you are seeing is that the python launcher is running your program and keeping the window
open so that you can read what it printed.

Often new users complain that the Window flash and vanishes before they can read the output.
This behaviours looks to be the solution to that common problem.

Hey Guy,

From Finder, right click on your `.py` file, then press the Option key.
You should see an ?Always open with?? menu item.
From that, select a Python Launcher.
A window will then pop up with a customisation dialog.
This has an option to ?Run in a Terminal Window?.

Good Luck.

Subject: [Pythonmac-SIG] py2app: Can successfully create app with alias mode
 but version built for deployment returns an error message
Message-ID: <CAPYR40LcS0NR8XKTa-Ca8uOaH7QvUhafekDvT8nCeu85UqWYog@mail.gmail.com>

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:

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

A quick guess: maybe pandas doesn?t like to be included into a py2app application in this way? I think `.pyx` files are Cython sources, and I think these need to be compiled on installation (which should have happend during py2app?).

When you google for ?pandas py2app? you?ll find people reporting similar (but not identical) problems to what you report.

But note that some of the stuff google finds is very old, so use your common sense, the world may have changed a lot since the link was written.

Yes, they are. But Cython is designed to show the source line number when
there are errors. So this has been compiled.

That error is vaguely familiar to me, I got it recently? I think the fix
was to clean out and recompile the Cython files.

However, if Pandas is working outside py2app, then it did get built
properly.

I?d look at the app bundle and see what?s different from the regular
install.

Ideally, it would copy only the complied modules.

No matter what I do, it does not load MainMenu.

Pointers?

Updating py2app from 0.21 to 0.24 did the trick.
