Can't run macOS binary after packaging

[Elliott Balsley]

I was previously running Python 3.7 from MacPorts with Pyinstaller 4.0 from pypi and this was working fine.  But after reading about Tkinter and Cocoa, I decided to wipe that away and install Python 3.7 from python.org instead.  Now Pyinstaller isn't working.  This is probably due to some configuration issue with my paths, but I would appreciate any advice.  I've removed all references to MacPorts Python that I can think of.

Inside a new venv I run

pip install https://github.com/pyinstaller/pyinstaller/archive/develop.zip

I make a very simple python script called bonk.py with just a single print statement.  Pyinstaller packages with no errors in onedir mode.  Here is the error when I try to run it:

$ ./dist/bonk/bonk 

[2616] Error loading Python lib '/Users/elliott/source/test1/dist/bonk/Python': dlopen: dlopen(/Users/elliott/source/test1/dist/bonk/Python, 10): no suitable image found.  Did find:

/Users/elliott/source/test1/dist/bonk/Python: code signature invalid for '/Users/elliott/source/test1/dist/bonk/Python'

There seems to be something wrong with the binary:

$ ./dist/bonk/Python 

-bash: ./dist/bonk/Python: cannot execute binary file

Some more details:

$ which python

/Users/elliott/source/test1/env/bin/python

$ python --version

Python 3.7.9

I have the same problem, both with Python 3.7.9 and Pyinstaller 4.0, and also with Python 3.8.6 and Pythinstaller 4.1.dev0.

I signed my app first, using codesign --deep, but it is the Python exe within the app that gives the error.

Has anyone solved this problem?

I went back to Python 3.7.3 (still with Pythinstaller 4.1.dev0) and the problem disappeared. Seems later versions of Python after 3.7.6 are problematic.

Hi,

there is an explanation and even a workaround now, see https://github.com/pyinstaller/pyinstaller/issues/5062
