How to convert kivy application to exe with --windowed mode ? there are some errors

Question

I'm using python 3.8 ,and kivy version is 2.2.1 , I tried to convert a little kivy application to exe using pyinstaller.

if I used this command > pyinstaller main.py it's working normally without raise any error, but it show the console. I don't want it.

if I use --windowed , -w or --noconsole flags the software raise an error.

Traceback (most recent call last):
  File "logging\__init__.py", line 1084, in emit
AttributeError: 'NoneType' object has no attribute 'write'

During handling of the above exception, another exception occurred:

There was a change in the most recent version of pyinstaller, you can read about the issue and fixes here: https://github.com/kivy/kivy/issues/8074

At top of your main.py file, before importing any kivy files add:

import os
import sys
if hasattr(sys, '_MEIPASS'):
    os.environ['KIVY_NO_CONSOLELOG'] = '1'
