AttributeError: 'API' object has no attribute 'followers_ids'

Question

I am trying to extract a list of followers from a particular user using Tweepy. However, I ran into an error saying that AttributeError: 'API' object has no attribute 'followers_ids'. This code, however, runs smoothly on another machine but not on mine. I tried to reinstall Tweepy but nothing changed. Please help T.T

    import os
    import sys
    import json
    import time
    import math
    from tweepy import Cursor
    import tweepy
    from tweepy import OAuthHandler
    import datetime
    
    auth = OAuthHandler(consumer_key, consumer_secret)
    auth.set_access_token(access_token, access_token_secret)
    api = tweepy.API(auth, wait_on_rate_limit=True)
    
    MAX_FRIENDS = 10000
    
    def paginate(items, n):
        """Generate n-sized chunks from items"""
        for i in range(0, len(items), n):
            yield items[i:i+n]
        
    def get_followers(screen_name):
        # get followers for a given user
        fname = "users/{}/followers.json".format(screen_name)
        max_pages = math.ceil(MAX_FRIENDS / 5000)
        with open(fname, 'w') as f:
            for followers in Cursor(api.followers_ids, screen_name=screen_name).pages(max_pages):
                for chunk in paginate(followers, 100):
                    users = api.lookup_users(user_ids=chunk)
                    for user in users:    
                        f.write(json.dumps([user.id, user.screen_name, user.location, str(user.created_at)], sort_keys=True)+"\n")                 
                if len(followers) == 5000:
                    print("More results available. Sleeping for 60 seconds to avoid rate limit")
                    time.sleep(60)
        print("task completed for " + screen_name)

Tweepy v4.0.0 renamed API.followers_ids to API.get_follower_ids.

You're likely using an older version of Tweepy on the other machine.
