TypeError: expected str, bytes or os.PathLike object, not WindowsPath while converting .py using Pyinstaller

While trying to build an .exe using Pyinstaller, this error is thrown:

I have found a solution posted on the Stackoverflow which states that there needs to be inserted a code into the backend.py in the Pyinstaller folder. But that does not work either.

What is going wrong here?

Solution

  • So, I found out that matplotlib was the issue. Excluding that in the module argument in Pyinstaller fixed it.

    Like this:

    pyinstaller --exclude-module matplotlib main.py
