How to solve the problem of wav resource loading failure when PyInstaller packages Tkinter program?

PyInstaller packages Tkinter program and wav resource loading problem solution

When using Tkinter to develop GUI programs and integrate audio resources (such as WAV files), the problem of WAV file failure to load after PyInstaller is packaged. This article provides an effective solution.

Problem description: Use --add-data "a.wav;." parameter to package the Tkinter program, but the WAV file still cannot load normally.

Solution:

1. Change the packaging parameters: Replace the --add-data parameter with --add-binary . This ensures that the WAV file is correctly embedded into the executable file, rather than being processed as a normal data file.

2. Modify the code: Add the following code snippet to the program to dynamically obtain the correct path to the WAV file:

    import sys
   import os
   
   try:
       base_path = sys._MEIPASS
   except Exception:
       base_path = os.path.abspath(".")
   wav_path = os.path.join(base_path, "a.wav")

   This code first tries to get the temporary directory path sys._MEIPASS after PyInstaller is packaged. If it fails (indicates that the program is not running in package), the absolute path to the current working directory is used. Finally, the wav_path variable stores the correct path to the WAV file.

Through the above two steps, the problem of WAV resource loading failure when PyInstaller packages the Tkinter program can be effectively solved, ensuring that the program can play audio correctly.
