How to fix: AttributeError: module 'twint' has no attribute 'Config'

I have installed twint with:

pip3 install twint

which resulted in a successful installation:

Successfully installed twint-2.1.13

It works to get tweets from twitter using Command Prompt(CLI) commands but when I try to run the example using a Python file as app.py it gives me the error:

Traceback (most recent call last):      File "app.py", line 82, in <module>          main()      File "app.py", line 77, in main          echo_all(updates)      File "app.py", line 48, in echo_all          send_message(text, chat)      File "app.py", line 64, in send_message         c = twint.Config()  AttributeError: module 'twint' has no attribute 'Config'

Here is how my app.py file looks like:

import twintc = twint.Config()c.Username = "twitterAccountName"twint.run.Search(c)

However, I looked twint related issues on GitHub found here but the solution provided here not worked for me. Does anyone know where the error coming from? How do I fix it?
