pyinstaller error - AttributeError: module 'pytest' has no attribute 'freeze_includes'

Question

I want to make my python file to exe file, though I got an error. I tapped pyinstaller -w file.py in my cmd screen, then I got an error like below.

    Traceback (most recent call last):

I added import pytest in my python file, but there's no change. Please let me know about the error.

Answer 1

This issue is caused by an out of date version of pytest. I was able to resolve it by using pip uninstall pytest and pip install pytest one after the other to update to the lastest version of pytest.
