Mac DMG quits immediately after opening

[mdegenero]

Hi @maltfield --

I ran the application through to create executables, but when I tried to open the dmg from helloWorld-mac-x86_64, it immediately quits after opening. It doesn't look like there were any errors outputted with the PyInstaller command. Do you know what might be causing this issue?

My project contains two python files and a .kv file, as well as a few .pngs. I can upload any relevant logs or files, if that will help.

It quits after opening the .dmg or the .app? It can happen after opening the .app from the GUI. My best-guess is that it's an issue with (lack of) notarization.

What version of MacOS are you running?

Please link me to the relevant GitHub Actions output.

Try opening the executable directly using the command-line to see if it produces additional output.

open -W helloWorld.dmg
open -W /Volumes/helloWorld/helloWorld.app/Contents/MacOS/helloWorld

Wait, where's your python files? You need a main.py at least..

My bad, I had made a few changes and forgot to re-upload. Just ran through the Actions again: https://github.com/mdegenero/cross-platform-python-gui/runs/962485463?check_suite_focus=true

When I try to open helloWorld.app, I get the following error:

File "virtual_ensemble.py", line 38, in
import numpy as np
ModuleNotFoundError: No module named 'numpy'

I see you've already added numpy to your requirements.txt file, and the output from the Actions you linked-to shows that it is being installed.

What I don't understand is why both main.py and virtual_ensemble.py import numpy, yet the error you get is only for virtual_ensemble.py, which--if numpy is truly missing--it should error-out on main.py first.

PyInstaller should clearly be able to find your numpy imports, but try adding it explicitly by adding it to hiddenimports

• https://github.com/mdegenero/cross-platform-python-gui/blob/892ba4378dd13b924a63634cd5154b307aeeffd2/build/mac/buildDmg.sh#L86

Change

hiddenimports=['pkg_resources.py2_warn'],

to

hiddenimports=['pkg_resources.py2_warn', 'numpy'],

If that doesn't work, try googling for PyInstaller issues and this error message. If you find a solution, please post back here so others can benefit from it.

I added the line "pip install --user --upgrade --force-reinstall numpy" to the buildDmg.sh file and that seemed to get rid of the numpy error. I am now getting a similar error, but for matplotlib:

"ModuleNotFoundError: No module named 'matplotlib'"

[mdegenero]

So, I got the same "ModuleNotFoundError" for all of my Python imports; so I added the --force-reinstall command for all of those imports, manually, in the buildDmg.sh file. I am now getting the following error:

added the line "pip install --user --upgrade --force-reinstall numpy" to the buildDmg.sh file and that seemed to get rid of the numpy error

I updated the buildDmg.sh script to use the --force-reinstall command when installing the depends listed in requirements.txt -- please test to see if this fixes your issues without having to add your modules one-by-one to the buildDmg.sh file

NameError: name 'defaultParams' is not defined

As for this, first confirm that your code itself doesn't have errors by running pythonX main.py before the build.

And if this is PyInstaller-specific, then please search the internet for the error and update this ticket with your findings for the benefit of others

Closing this. Please re-open if this is indeed an issue with this repo.

And please add comments if you solved your issues with PyInstaller/matplotlib
