Pyttsx3 not working with PyInstaller - python-3.x

Question

I get this error from the exe generated by PyInstaller when using Pyttsx3. The code works fine in python. I've tried using other versions of PyInstaller and Pyttsx but it doesn't make a difference. I've also tried Py2exe which is also not working with Pyttsx3, does anyone know what's causing this?
The code
import pyttsx3
engine = pyttsx3.init()
engine.say('Test')
engine.runAndWait()
The error after running the exe generated
Traceback (most recent call last):
File "site-packages\pyttsx3\__init__.py", line 44, in init
File "c:\python34\lib\weakref.py", line 125, in __getitem__
o = self.data[key]()
KeyError: None
During handling of the above exception, another exception occurred:

Answer 1

Try this:
import pyttsx3
from pyttsx3.drivers import sapi5
engine = pyttsx3.init()
engine.say('Test')
engine.runAndWait()
Explanation:
You actually need to import an extra module from pyttsx3.

Answer 2

Goto location:
C:\Users\username\AppData\Local\Programs\Python\Python38-32\Lib\site-packages\PyInstaller\hooks
Create a newfile "hook-pyttsx3.py"
inside file, copy the code below..

""" 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', ]
Now your program will run without getting error.

Answer 3

Try this:
pyinstaller --hidden-import=pyttsx3.drivers --hidden-import=pyttsx3.drivers.dummy --hidden-import=pyttsx3.drivers.espeak --hidden-import=pyttsx3.drivers.nsss --hidden-import=pyttsx3.drivers.sapi5
Hidden import argument for pyinstaller import 3 rd party packages into build. By adding above lines to pyinstaller will create a spec file with hidden-import =[‘pyttsx3.drivers’,’pyttsx3.drivers.dummy’,....] which will rectify the error “no module named pyttsx.driver’ but eventually u will end up other error also which i am unable to solve.

Answer 4

I've just fixed pyttsx3 compatibility in #101. In a couple of weeks you will be able to:
pip install "pyinstaller-hooks-contrib>=2021.2"
but until then you can use the Github version:
pip install -U https://github.com/pyinstaller/pyinstaller-hooks-contrib/archive/refs/heads/master.zip
Add the --clean option the first time you run PyInstaller after using pip (unless you're using auto-py-to-exe which blocks PyInstaller's caching). It should then work on all platforms without using any --hiddenimport-ing.
