py2app: Can successfully create app with alias mode but version built for deployment returns an error message
by Paul Fishback June 17, 2021

June 17, 2021

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 % ./dist/MyApplication_6_15.app/Contents/MacOS/MyApplication_6_15 Traceback (most recent call last): File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/__boot__.py", line 115, in <module> _run() File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/__boot__.py", line 84, in _run exec(compile(source, path, "exec"), globals(), globals()) File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/MyApplication_6_15.py", line 6, in <module> import pandas as pd File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/lib/python3.9/pandas/__init__.py", line 179, in <module> import pandas.testing File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/lib/python3.9/pandas/testing.py", line 5, in <module> from pandas._testing import ( File "/Users/fishbacp/Desktop/Python_May_2021/dist/MyApplication_6_15.app/Contents/Resources/lib/python3.9/pandas/_testing.py", line 29, in <module> import pandas._libs.testing as _testing File "pandas/_libs/testing.pyx", line 1, in init pandas._libs.testing ValueError: source code string cannot contain null bytes I'm curious to know if anyone has insights regarding the last line in the above message.

Jack Jansen - Question on Python Launcher
by Guy DeStefano June 2, 2021

June 2, 2021

Sorry to bother you, but I have one question that I cannot find an answer to, could you please help. Am very new to Python3 and have written a small program that is my base for my learning Python3. All is perfect except, when I double click my program the .py file, it works great except that it calls in the Python Launcher, and when I exit my program, the preferences box for Python Launcher and the Icon of the launcher still remain on the screen. I have to manually close the python launcher. Can this be done programmatically, I exit with sys.exit(0). I am using tkinter in the program, along with python3.9.5, on an Apple Mac computer. This may not be the proper place for this question, if not, I apologize and please direct me where to go as I have been googling for days. Thanks in advance. Any help will be greatly appreciated. I have just noticed that python3 -V states python 3.9.5, and looking at the python launcher box it states Version 3.10.0b1(3.10.0b1) Is this something I am doing wrong. guydestefano(a)gmail.com Guy DeStefano
