Pyinstaller error after updating latest PySide

Question

I have a working python(3.6.8) and Pyside(5.12.0) application.

Previously I was able to create one file exe and its run fine.

But after updating Pyside to 5.12.2 I am not able to run app. there is ModuleNotFoundError: No module named 'typing'

I already have typing module installed(pip install typing). I tried to uninstall pyside(5.12.2) and reinstall pyside(5.12.0)

but still i am getting same error. Here is the error.

I had exactly the same problem with cx_freeze. After the build of the cx_freeze application and running I got the error:

Problem importing shibokensupport:
No module named 'typing'
Traceback (most recent call last):
  File "(builtin)", line 93, in ensure_shibokensupport
  File "(builtin)", line 133, in bootstrap
  File "/tmp/embedded.mp0z2vy0.zip/shibokensupport/signature/loader.py", line 156, in <module>
    import typing

I added typing manually to the packages which need's to be included in the cx_freeze setup.py :

# -*- coding: utf-8 -*-

import sys
from cx_Freeze import setup, Executable

options = {
    'build_exe': {
        'packages': [
            'os',
            'typing'
        ],
        'excludes': [
            'tkinter'
        ]
    }
}

base = None

if sys.platform == 'win32':
    base = 'Win32GUI'

executables = [
    Executable('qt_test1.py', base=base)
]

setup(
    name='qt_test1',
    version='0.1',
    description='My GUI application!',
    options=options,
    executables=executables
)

This does it. It run's now.

It means for PyInstaller you have to call it in this way:

$ pyinstaller your_app.py --hidden-import="typing"

Actually, I do not know if there is a better way for PyInstaller to explicit add modules to the building process.
