Pyttsx3 worked earlier but not now

Question

In december, 2019, my pyttsx3 module was working fine with no error. After few months I uninstalled Python, But in May 2020 I installed it again. But this time, wierd errors came... My os is win10Pro , Python 3.7(earier it was the same), IDE is Pycharm. The code is :

import pyttsx3


def speak(text):
    engine = pyttsx3.init()
    engine.say(text)
    engine.runAndWait()


speak("Hello World!")

When I run it :

Traceback (most recent call last):
  File "C:\Users\Romoni Gogoi\AppData\Local\Programs\Python\Python37\lib\site-packages\pyttsx3\__init__.py", line 20, in init

I didn't get it. What shoud I do? If you know how to solve it, Please share it with me..

This may help. You should try installing tools for Python. By this I mean the Dev and other dependecies. One way to install python Dev tools is apt-get install python-dev if this didn't work, you will do this same thing but with the python version.
