Requests works locally but not deployed on Heroku

Question

This code works locally, but when I deploy it to Heroku, I get ModuleNotFoundError: No module named 'requests'. (Note: urllib.parse works fine — news_link prints.)

   import urllib.parse as url_parse
    url = rurl
    news_link = url_parse.unquote(url).split("?u=")[1].split("?fbclid")[0]
    print("here comes the news_link")
    print(news_link)
    import requests
    final_link = requests.get(news_link)
    print("here comes the final_link.url")

Answer 1

It looks like you forgot to include requests in the requirements.txt file, check if it is there and in case it is you can try opening the bash console using this answer indications and run a pip freeze to see if it actually is installed or not.
