Today, I want to share my experience with resolving the "ModuleNotFoundError" while converting a Python script into an executable.

I developed a desktop application in Python using Tkinter and several other modules. My goal was to package it as a standalone executable so others could use it without installing any dependencies.

To achieve this, I used PyInstaller and ran the following command in the Command Prompt from the directory containing my Python file. Unfortunately, this resulted in a "ModuleNotFoundError" and the build failed.

The Command I used: pyinstaller --onefile --noconsole file.py

CMD Output:

Solution That Worked for Me

After trying multiple approaches, the method that resolved this issue was simple:

I ran the same PyInstaller command from the IDE's integrated terminal instead of the Command Prompt, and It worked for me.

If you encounter the same error, I recommend executing the PyInstaller command in your IDE's terminal.

Hey,
The problem should be the module import in pyinstaller.
I think, you can use spec instead of using flags. You can add binaries and custom packages here.
You can find the detail about the configuration here.
Hope this solves the problem you faced.
Thank you in advance.
