Aborts on macOS 13.2.1 with couldn't recognize data in image file iconmonstr-location-27-32.png about pygpsclient

Hi @richardklingler

Sorry you're having difficulties, but I can only imagine you have a corrupted installation somehow.

PyGPSClient runs fine under MacOS 13.2.* on both Intel and M1/M2 platforms and Python versions >=3.7, <=3.11. The image file in question appears in the About dialog - see screen shots below.

I've not come across that 'Tk deprecation' warning before on a Mac - there may be something odd about your Python installation. It may be worth upgrading to the latest Python 3.11 (alongside 3.9 if necessary) to see if that resolves the problem, or re-installing Python 3.9 via the Mac 64-bit Universal Installer (https://www.python.org/ftp/python/3.9.13/python-3.9.13-macos11.pkg).

Fiddled around a bit and tried installing 3.11.2 via pyenv...no joy...

Only this helped:

brew install python-tk

Hi @richardklingler

Glad you got it sorted, but I'm surprised you had to do a brew install of python-tk on MacOS - this is typically only necessary on some Linux platforms.

The standard universal Python installation package for MacOS (from python.org, not the App Store) includes all the necessary tkinter runtimes and environment configuration. I've never needed to install brew or macports on any of my Mac workstations.

Hi @brandonros

The clue is in the error message:

DEPRECATION WARNING: The system version of Tk is deprecated and may be removed in a future release. Please don't rely on it. Set TK_SILENCE_DEPRECATION=1 to suppress this warning.

As is mentioned in the README.md, the version of Python that is preinstalled on MacOS includes a deprecated version of tkinter (8.5). God only knows why - it's been deprecated for nearly 10 years now. You'll need to upgrade this to the latest version 8.6, and by far the easiest way to do this is to simply install Python using the official Python.org MacOS 'universal2' installer, which works for both Intel and Apple Silicon:

https://www.python.org/downloads/release/python-3114/

I STRONGLY RECOMMEND against using brew or macports to install python or tkinter - that will almost certainly lead to a corrupted installation.

If you want to check the version of tkinter you're running, you can run the following script:

import tkinter
tkinter.TkVersion

To find the low level version, use:

import tkinter
tcl = tkinter.Tcl()
print(tcl.call("info", "patchlevel"))

Hope this helps
