Pyinstaller: ModuleNotFoundError: No module named 'wmi'; getting several modules not found errors

Question

The command that I am running is pyinstaller --log-level DEBUG beforeLogin.py

When I try and run the executable created using command line I get:

Traceback (most recent call last):
  File "beforeLogin.py", line 2, in <module>
ModuleNotFoundError: No module named 'wmi'
[18908] Failed to execute script beforeLogin

I am not sure how to build my own .spec file but here is the one created by pyinstaller:

# -*- mode: python ; coding: utf-8 -*-

block_cipher = None


a = Analysis(['beforeLogin.py'],
             pathex=['C:\\Users\\prana\\Desktop\\GUIApp'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher,
             noarchive=False)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          [],
          exclude_binaries=True,
          name='beforeLogin',
          debug=False,
          bootloader_ignore_signals=False,
          strip=False,
          upx=True,
          console=True )
coll = COLLECT(exe,
               a.binaries,
               a.zipfiles,
               a.datas,
               strip=False,
               upx=True,
               upx_exclude=[],
               name='beforeLogin')

My warn-beforeLogin.txt file located in GUIApp\build\beforeLogin:

This file lists modules PyInstaller was not able to find. This does not
necessarily mean this module is required for running you program. Python and
Python 3rd-party packages include a lot of conditional or optional modules. For
example the module 'ntpath' only exists on Windows, whereas the module
'posixpath' only exists on Posix systems.

Types if import:
* top-level: imported at the top-level - look at these first
* conditional: imported within an if-statement
* delayed: imported from within a function
* optional: imported within a try-except-statement

IMPORTANT: Do NOT post this list to the issue-tracker. Use it as a basis for
           yourself tracking down the missing module. Thanks!

Even, I am facing similar issues. What I understood so far is that we need to add hooks files for each module missing. Its painful, if this is the soln offered by pyinstaller. Even standard modules of numpy are not available ....

In your entry script beforeLogin.py, try doing this

import pythoncom
pythoncom.CoInitialize()
import wmi 

I had an issue bundling wmi as well and the above worked for me.
