Twint Python library is causing exception for search query – Twitter API

I have to collect some data from Twitter via Search. Unfortunately, its not possible to get Twitter API as they have rejected my request many times. I have decided to use twint python module for this purpose. I have installed latest version via git and then tried to search tweets for a string as follows:

twint -s pineapple

I get this exception

Traceback (most recent call last):

TypeError: Argument should be str

The installed version of python on my Ubuntu is 3.6. I have also imported twint in Python script but same exception appeared there also.

How to fix this issue ? Is there any best alternate for this task ?
