在Tweepy中关注用户无输出

Question

我在Python 3.6中有代码，并且正在尝试使此代码正常工作，这并不是我遵循的用户指定的推文。我从正常运行的代码中提取了此代码的基本结构，该代码从全局twitter流中跟踪了关键字。下面的代码行由于无法接收流而无法正常运行。

stream.filter(follow=[user_id])

以下是完整的代码，仅供参考。

import settings
import tweepy
import dataset
import datetime
import time
from textblob import TextBlob
from sqlalchemy.exc import ProgrammingError
import json

print("Starting scraper.py")
db = dataset.connect(settings.CONNECTION_STRING)
print("Connected to dataset")

        loc = status.user.location
        text = status.text
        coords = status.coordinates
        geo = status.geo
        name = status.user.screen_name
        user_created = status.user.created_at
        followers = status.user.followers_count
        id_str = status.id_str
        created = status.created_at
        retweets = status.retweet_count
        bg_color = status.user.profile_background_color
        blob = TextBlob(text)
        sent = blob.sentiment

        if geo is not None:
            geo = json.dumps(geo)
