ModuleNotFoundError: No module named 'pyttsx3.drivers' (File Compiled with pyinstaller), but working fine as uncompiled

Question

I compiled my program using pyinstaller, python file working fine when not compiled, but throwing the error when i compiled & tested it.

This is the full error, I think this might be because of pyinstaller

Traceback (most recent call last):
  File "site-packages\pyttsx3\__init__.py", line 20, in init
  File "c:\python37\lib\weakref.py", line 137, in __getitem__
    o = self.data[key]()
KeyError: 'sapi5'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "song_dl.py", line 25, in <module>
    engine = pyttsx3.init('sapi5')
  File "site-packages\pyttsx3\__init__.py", line 22, in init

Answer 1

First, go to the folder where your python.exe file is installed, then go to this directory:

\Lib\site-packages\PyInstaller\hooks

You have to install pyinstaller first before going into the directory. Then look in the hooks folder and see if there is a file named:

hook-pyttsx3.py

There is a strong possibility that the file might not be present. So, you have to create hook-pyttsx3.py in the hooks folder and in the file you have to write:

""" pyttsx3 imports drivers module based on specific platform. Fount at https://github.com/nateshmbhat/pyttsx3/issues/6 """


hiddenimports = [
    'pyttsx3.drivers',
    'pyttsx3.drivers.dummy',
    'pyttsx3.drivers.espeak',
    'pyttsx3.drivers.nsss',
    'pyttsx3.drivers.sapi5', ]

Save the file. Then run your code. The problem will be solved (at least it worked for me.) This problem came because pyinstaller is not updated officially to use python 3.8 fully, so hooks of some modules are missing
