"Failed to execute script " pyinstaller

I have a python code that I wanted to turn into an exe.
I used pyinstaller with : pyinstaller --onefile -w script.py
After it finished making the exe file I double clicked the file but I got "Failed to execute script".

I also tried running it from the cmd but it gives the same fatal error.

Stuff to add:
The code imports a couple of files packages including a python code I made, as well as it makes files referenced to it's location.

Is there something I'm doing wrong?

the script has those imports:

import socket
import os
from PIL import ImageGrab
import cv2
import time
import json
import myFile

I ran the code under cmd and it gives this error:

  File "script.py", line 3, in <module>
    from PIL import ImageGrab
ModuleNotFoundError: No module named 'PIL'

Might be unrelated but now that I tried to do pyinstaller --onefile -w client.py.
After I ran it windows defender found this inside :

after running it in the terminal in pycharm with :

pyinstaller --onefile --hidden-import=PIL --hidden-import=Pillow --hidden-import=pynput client.py

I get this error (note that i moved it from the dist directory to the main one):

Solution

  • This may be due to pyinstaller not being able to properly find your dependencies and skipping some packages.

    To fix any error like ModuleNotFoundError: No module named 'PIL' just add it as a hidden import:

    pyinstaller --onefile --hidden-import=PIL -w script.py

    For the second error this is a known issue with pyinstaller and pynput. Find here some explanation.

    The TLDR of it seems to be that you need to add --hidden-import=pynput.mouse._win32 --hidden-import=pynput.keyboard._win32 --hidden-import=pynput._util._win32 and any other sub-packages that give you errors.
